Also when it gives you an equation and tells you to put the solution in an expression , you can solve for the coefficient times the variable by multiplying a certain number by the variable Example If 7x=14 then 21x+2 is Multiply both sides by 3 21x=42 (42) +2 = 44

if x1,x2,x3 are the roots of ax^3+bx^2+cx+d, the sum is -b/a, the sum of their pairwise products(x1x1+x2x3+x1x3) is c/a and the product is -d/a

[@varadprasad6986]

Wow she practically uses collgate all-day

[@mahimaruf9780]

for the sum of all values on that second example, you guys could also remember that if you make it into ax^2-bx-c where your a should be 1, your b is also negative sum of solutions and your c is the product of the solutions so you couldve solved it in two seconds by factoring out the 2 as she did and see that 8 was your negative sum, therefore since you have a double negative its just 8

Okay guys i finished the sat. I originally also chose to do the essay but opted out. Anyway i was primarily studying on khan academy and the sat collegeboard book. Khan academy to me makes the test seem harder than it is. The test quite easy with some challenging questions. I'll update you guys with my score on December 20th. (Btw this is my first time taking it)

[@user-en7dx1qp3k]

8:45 you don't need the quadratic formula to derive vieta's formulas, i will show here (it works for all degrees of polynomials): ax^n+bx^(n-1)...+q =0 where q is the constant. if r_1, r_2,...,r_n are the roots, the original equation is factored as a(x-r_1)(x-r_2)...(x-r_n). this expands out into a(x^n-(r_1+r_2+...+r_n)x^(n-1)...). this expands further into ax^n-a(r_1+r_2+...+r_n)x^(n-1)...+q=0 so b=-a(sum of roots). the sum of the roots is therefore -b/a. The product is derived similarly as +- (q/a). + if n is even, - if n is odd. Even more interestingly, r_1*r_2 + r_2*r_3...+r_n*r_1 = c/a where c is the third term. r_1*r_2*r_3+r_2*r_3*r_4+... + r_n*r_1*r_2 = -d/a where d is the 4th term, etc. also, it's called a discriminant, not a determinant. you use determinants in linear algebra. (this is not a stupid formula.)

[@sebastianrusso283]

For question 13, I find it may be easier to approach the problem by factoring through completing the square. Then you can do some easy mental math to figure out which values of x will make the equation true for 0 = 0. :)

Answer =8 (1:27) x^a^2- b^2 (the rule of exponent as x^y/x^n = x^y-n) x^(a+b)(a-b) {factor a^2-b^2 which equals (a+b)(a-b)} x^ 2(a-b) (substitute a+b = 2 given) x^2a-2b = x^16 2a-2b=16 a- b = 8 (divide both sides by 2) PS provided you know the quotient rule of exponent, can factor the difference of squares, (then you substitute a+b for 2), and then equate the exponent (such as if x^n+1= x^2, then set n+1=2, hence n=1) YOU will get it.

Here is a hard SAT algebra question For a positive real number, x, where x^8 = 2, what is the value of x^24? A) cube root of 24 B) 4 C) 6 D) 8

[@anudeepannangi9813]

@andrewcalfa The right answer is D) 8. To isolate x in the first equation, we must take the 8th root of x on both sides, therefore x = 8th root of 2. We can rewrite x as 2^(1/8) . Now, we plug 2^(1/8) into the second equation. After plugging it in, it should look like this: ( 2 ^ (1 /8) ) ^ 24. This simplifies to 2^3 which is 8.

[@ssharpphd3054]

Raise both sides of the equation to the third power. (x^8)^3 = x^24 = 2^3 = 8. It is the "power of a power" rule in some texts. When a power is raised to another power, you multiply. 8*3=24.

[@hilator4657]

Any algebra 2 textbook and many places online, I’m sure. It’s a very simple concept though - if you have an equation where the exponents on each side have the same base but a different power, then those powers must equal each other, so you can just set them equal to each other and “drop the bases.” For instance, if 2^3=2^x-1, then 3=x-1, and x=4.
