Question

Factorize:

a) x^2+9x+18


b)6x^2+7x-3

Answer 1

1
${x}^{2} + 9x + 18 \\ {x}^{2} + 3x + 6x + 18 \\ x(x + 3) + 6(x + 3) \\ (x + 6)(x + 3)$
2
$6 {x}^{2} + 7x - 3 \\ 6 {x}^{2} + 9x - 2x - 3 \\ 3x(2x + 3) -1 (2x + 3) \\ (3x - 1)(2x + 3)$

Answer 2

Hola Mate !!

Here's your answer :-

${x}^{2} + 9x + 18 \\ = > {x}^{2} + 6x + 3x + 18 \\ = > x(x + 6) + 3(x + 6) \\ = > (x + 6)(x + 3)$

${6x}^{2} + 7x - 3 \\ = > {6x}^{2} +9x - 2x - 3 \\ = > 3x(2x + 3) - 1(2x + 3) \\ = > (2x +3)(3x - 1)$

Hope it helps
