Question

Factorise x2+5x+6 using appropriate identities

Answer 1

Answer:

$- 3 \: and \: - 2$

Step-by-step explanation:

${x}^{2} + 5x + 6$

finding x through factorisation method

$6 = 2 \times 3$

$2 \times 3 = 6 \: and \: 2 + 3 = 5$

it a quadratic formula so it have two x

$(x + 2)( \times + 3)$

$x = - 3 \: and \: x = - 2$

Answer 2

Step-by-step explanation:

x^2+5x+6=0

x^2+3x+2x+6=0

x(x+3)+2 (x+3)=0

(x+3)(x+2)=0

(x+3)=0 Or (x+2)=0

x=-3 Or x=-2
