Small mistake at 4:50 but luckily it does not effect the final answer. I said +B instead of -B. But B will still end up as 0.

2 is also a factor

To make your lives a bit easier, just use Mode-5-4 to get the x-intercepts

Can you just use synthetic division to find the intercepts?

when guessing for the 1st x-int, cant we use the factors on the last number ? great lesson btw i got exactly what i needed!!!

Yes that is a nice technique that I have now started doing as well :) Saves time!

Hey Kevin i did grouping for the x-intercepts a it worked,does it work every time or should i follow your technique

Hi! Your video was insanely helpful thank you so much! Although my question is where do we get the quad equation 3x^2 - 2x -4 from?

Hello :) That is after I took the first derivative of the original function :)

Helo uncle Kev, for this question I made f(x)=0 and didn’t sub in the X values.So 0=(x+3)(x-1)(x-1) and then simplified into the actual formula, is that alright or do I have to use your way with the a and triple brackets? When they give x intercepts I mean-I’ll have to use your way if they don’t

Hey Kevin,thanks for the amazing lesson I understood everything,but the part I don't get is why you didn't calculate the inflection point?
@Sean-t5j11 ай бұрын
The inflection point is the middle x-intercept

Why do we use quadratic formula to find the turning point and not the regular formula for a tp

after getting the (x-1) can I factorize the other bracket instead of using the formula?

Sometimes :) Other times it wont work out as the answers will be decimals etc...

Good sir I just wanna ask for f(x)=x^3-x^2-4x+4 instead of this method; 0=(x-1)(AX^2+BX^2+C), why can't you use grouping to factories f(x)

If you multiply - 1 by by b won't it give you - b? This is confusing please give me clarity on that.
@lynk2572 Жыл бұрын
It's a mistake but doesn't affect the final answer B still ends up as 0

I think made a mistake, theres no point of inflection
