same tho lmao

This was the best explanation of this anywhere

[@justinchen3076]

When trying to find the x-intercepts, you flipped the factors. In that process does the +/- of the numbers matter?

[@rademakermath2748]

The x-intercepts are always the opposite of the factors because they occur when y equals 0. So using the Zero Product Property you set each factor equal to zero and solve. x+5=0 results in x=-5

Thank you so much I have a test tmmrw and I have 1st period so I was like asleep much love

[@ryanolson3717]

Bro thx for this video, it was really great! I have a question at 7:47, if the number is composite, take 60 for example, how would we determine which numbers to take? (4, 15) (2, 30) (6, 10). I suspect you just take the numbers that aren't divisible, so 2, 30? Edit: Assuming we can't factor it out in the beginning. take something like 60x^2+7x+12

[@rademakermath2748]

Good question! There are a couple different techniques to factor if the Leading Coefficient isn't 1 or isn't prime. For something like 60x^2, using the quadratic formula might be the best option because 60 has so many factor pairs. Other methods include Factor by Grouping, Swing Method, or just Guess/Check with FOIL like in the video. Remember that not all quadratic trinomials are factorable. For example, your suggestion of 60x^2+7x+12 isn't factorable with real numbers.

[@ryanolson3717]

@@rademakermath2748 ok thank you so much! I was also wondering how you order the numbers? Is there a little trick you know to always do it correct?

[@rademakermath2748]

@Ryan Olson There's no real good trick. If you do FOIL enough, it's easier to tell what the Outside and Inside terms will combine to. You kind of just have to guess and see what works or doesn't work. But like I said there are some factoring techniques that you can search for and learn that will get the answer right away, although they take a couple extra steps.

thank you for this video. what is gcf?

[@victor6316]

WoW I like your hand writing so much !

[@thatonedummy5716]

does it matter which - becomes +? like in the first problem would 2(x+5)(x-3) work or am i just missing something?

[@rademakermath2748]

Yes, The +/- matters. The multiplication back needs to match the original problem.

[@thatonedummy5716]

I know it does, but does it matter which one is which, or as long as it matches@@rademakermath2748

[@skyflower833]

wait but can you use Maxx or not because I don't get it 😅

[@rademakermath2748]

I'm not sure I understand. What is Maxx?

[@skyflower833]

@@rademakermath2748 well Maxx is multiply, add and the two X's are the numbers that can equal the M and A in Maxx. Sorry if I didn't explain it well 😅 and thank you for responding

[@rademakermath2748]

@@skyflower833 It sounds like what we call Factor by Grouping, which should still work. As long as you can factor the trinomial (using any method) and pull out the 'A' value, you'll be able to get to factored form.

[@notoriousEDD8279]

what if you only have a and c

[@rademakermath2748]

That can still be factored, but the only options to factor are taking out a Greatest Common Factor or checking to see if it's a Difference of Squares.

How to get The Product of sum

[@rademakermath2748]

Find which two numbers multiply to the last term (C) and add to the middle coefficient (B). Just trial and error.
