Question

factorise and find the answer for x^2+3x-4 ​

Answer 1

Answer:

x = 1 or x =-4

Step-by-step explanation:

Given equation,

x² + 3x - 4 = 0

The method used here is middle term splitting

Thus we proceed as,

x² + 4x - x - 4 = 0

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

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

Thus we get, x = 1 or x = -4

Answer 2

solution=>

$= x {}^{2} + 3x - 4 \\ \\ = x {}^{2} - x + 4x - 4 \\ \\ = x(x - 1) + 4(x - 1) \\ \\ = (x + 4)(x - 1) = 0 \\ \\ = > x + 4 = 0 \\ \\ x = - 4 \\ \\ and \: x - 1 = 0 \\ \\ = > x = 1$

answer

$x = - 4 \: \: ,\: \: 1$
