Question

answer by using mid term spliting
x²+2x-3​

Answer 1

${x}^{2} + 2x - 3$

splitting middle term

${x}^{2} + x -3 x - 3 \\ \\ x(x - 1) - 3(x - 1) \\ \\ (x - 1)(x - 3)$

Answer 2

Step-by-step explanation:

x² + 2x - 3

x² + 3x - x - 3

(x² + 3x) - (x + 3)

x (x + 3) - 1 (x + 3)

(x-1)(x+3)

x = 1

OR

x = -3
