You can
put this solution on YOUR website! 4x2 = 35 - 4x
Add 4x to, and subtract 35 from, both sides to get 0 on the right
4x2 + 4x - 35 = 0
Factor the left side:
(2x + 7)(2x - 5) = 0
Use the 0-factor principle. Set each factor on the left = 0.
Setting 2x + 7 = 0
2x = -7
x = -7/2
Setting 2x - 5 = 0
2x = 5
x = 5/2
There are two solutions, -7/2 and 5/2
