Let m=5x-2.
which equation is equivalent to (5x-2)^2+35x-14=-12

a. m^2-7m+12=0
b. m^2+7m-2=0
c. m^2-7m-2=0
d. m^2+7m+12=0

D

Step-by-step explanation:

given

(5x - 2)² + 35x - 14 = - 12 ← factor out 7 from 35x - 14

(5x - 2)² + 7(5x - 2) = - 12 ( add 12 to both sides )

(5x - 2)² + 7(x - 2) + 12 = 0 ← substitute m = 5x - 2, hence

m² + 7m + 12 = 0 → D
