SOLUTION: a ^2 -2a = 35 = 0

Question 186989: a ^2 -2a = 35 = 0
Answer by rapaljer(4671) (Show Source): You can put this solution on YOUR website!
You have two equal signs in this equation. Did you mean a ^2 -2a - 35 = 0

If so, then factor the trinomial:
a ^2 -2a - 35 = 0
(a-7)(a+5) =0
a-7=0 or a+5=0
a=7 or a=-5

If you need detailed explanations on either "Factoring Trinomials" or "Solving Quadratic Equations" in an easier to understand format, then be sure to see my own website by clicking on my tutor name "rapaljer" anywhere in algebra.com. On my homepage, see the second link called "Basic, Intermediate, and College Algebra: One Step at a Time." Click on "Basic Algebra" and look in "Chapter 2" for the topics that you need on this subject. See also the "MATH IN LIVING COLOR" pages where many of the exercises are solved in "living color."
