Question

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)

Answer 1

so the factors of x²+3x-4 are (x-1)(x+4

Explanation:

Let x²+3x-4=0

by using sum and product rule

x²+4x-1x-4=0

Taking common

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

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

i hope this will help you :)

Answer 2

(x - 1) (x + 4)

Explanation:

Product = -4

Sum = 3

Factors = -1 , 4

x² + 3x - 4 = x²- 1x + 4x - 4

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

= (x - 1) (x + 4)
