Question

x square +3x+2factorise the following using appropriate identities ​

Answer 1

${x}^{2} + 3x + 2 \\ factor \: of \: 2 = 2 \times 1 \\ = {x}^{2} + 2x + 1x + 2 \\ = x(x + 2)1(x + 2) \\ = (x + 1)(x + 2)$

Answer 2

Step-by-step explanation:

x^2 + 3x +2

x^2 + 2x + 1x +2

x ( x + 2 ) + 1 ( x + 2 )

( x + 1 ) ( x + 2 )

x + 1 = 0

x = -1

x + 2 = 0

x = -2

x = -1 , -2
