x and B. and x B​

Answer 1

Answer:

♠️ Answer ♠️

$= {x}^{2} + 3x - 2 \\ \\ = {x}^{2} + 2x + x + 2 \\ \\ = x(x + 2) + 1(x + 2) \\ \\ = (x + 2)(x + 1) \\ \\ if \\ \\ x + 1 = 0 \\ \\ x = - 1 \\ \\ if \: \\ \\ x + 2 = 0 \\ \\ x = - 2 \\ \\ \alpha = - 1 \\ \\ \beta = - 2 \\ \\ \alpha + \beta = - 1 + ( - 2) = - 3 \\ \\ \alpha . \beta = - 1 \times ( - 2) = 2$
