how would u factor 2x^2 +13x-7 =27? please help
Let's take a look at your problem:
2x^2 + 13x - 7 = 27
First, set the equation equal to 0 by subtracting 27 from both sides of the equation (whatever operation you do to one side of an equation you must do to the other side as well):
2x^2 + 13x - 7 - 27 = 0
2x^2 + 13x - 34 = 0
Try to factor if possible:
(2x + 17)(x - 2) = 0
This factors nicely!
Next, set each factor equal to 0:
2x + 17 = 0
x - 2 = 0
Solve both for x (there will be 2 solutions).
I hope this will help.
