Step-by-step explanation:
x² + 3x - 15 = 2x - 13
x² + x - 2 = 0
(x + 2)(x - 1) = 0
By zero product rule, (x + 2) = 0 or (x - 1) = 0.
Hence x = -2 or x = 1.
Answer:
x = -2 & x = 1
Step-by-step explanation:
x^2 + 3x - 15 = 2x - 13 so you takeaway 2x and add 13 to the other side to get x^2 + x - 2 = 0
(x+2)(x-1) = 0 find factors of -2 that get you x
(x+2) = 0 so x = -2 (x-1) = 0 so x = 1
