Do these 5 problems for your project and SHOW ALL your work. You can either factor or do the quadratic formula. 3x^2 + 7x – 6 = 0 -x^2 – 2x + 8 = 0 -3x^2 – 2x – 5 = 0 x^2 – 1 = 0 x^2 + 4x – 7 = 0 (Last one you have to use quadratic formula) On each question tell what way you solved it and why.

How do you answer this question? (step by step)
