You can use the quadratic formula when you get you X's turn them into factors. Do you understand or do you need me to show you?

Well I'm struggling so I'd like you to show me please. :) @kelsey1

$$x^2 - 2x - 15 = 0$$
This factors into $$(x-5)(x+3) = 0$$.
 So $$x=5$$ or $$x=-3$$

anonymous · Answer

okay no problem I'll show you the steps!

anonymous · Answer

Awesome thank you very much! I was stuck on the factoring part. @rsnoob Any ideas for the second equation? @kelsey1

anonymous · Answer

1. $$2x2 -3x + 1 = 0$$

2. $$2x2 - 2x - x + 1 = 0$$

3. $$2x(x-1)-1(x-1)=0$$

4.$$( 2x-1) (x-1 ) = 0$$

5. $$X = 1/2$$ or $$x=1$$
