If (x+1) (x+4) - (x-2) = 0 what is the value of x?

A: - 1

B: - 1/4

C: 0

D:1/4

E: 1

(x+1) (x-4) - (x-2) = 0

x²-4x+x-4-x+2 = 0

x²-4x-2 = 0

/ / = (-4) ² - 4*1 * (-2)

/ / = 16 + 8

/ / = 24

x = ( - (-4) + / - / / 24) / 2

x = (4+/-//4*6) / 2

x = (4+/-2//6) / 2

x = 2+/-//6

x' = 2+//6

x" = 2-//6
