First we want to set the equation equal to zero by subtracting 36 from each side...
x^2 + 5x -36 = 0
Now we factor
(x + 9)(x - 4) = 0
Now set each expression equal to zero and solve...
x + 9 = 0 x - 4 = 0
x = -9 x = 4
Your solution set is
(-9, 4)
I'm guessing the equation is 2x^2-3x=-5
If this is the case, then you need to set the equation to equal 0 by moving the -5 to the left side of it
2x^2-3x+5=0
The you can factor the equation
(2x-5)(x+1)=0
now solve for each factor
2x-5=0 is x=5/2x
x+1=0 is x=-1
Answer:
-5 / 4
