Answer:

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

Step-by-step 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:

(x - 1) (x + 4)

Step-by-step 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)
