What are the factors of x2 + 3x - 4?

(x + 4) and (x - 4)

(x + 3) and (x - 4)

(x + 4) and (x - 1)

(x + 3) and (x - 1)

I get a list of zeroes: x = ± 1, - 3, 2 ... For instance, for x = 2 to be a solution, then I must have solved the factor equation x - 2 = 0, which means that x - 2 must have been a ... Find the quadratic with zeroes at x = 3 / 2 and x = - 5 / 4

X^2 + 3x - 4 =

x*x - x + 4x - 4 =

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

(x+4) (x-1)

so the 3rd choice is right sure
