Question

solve the question no 14,16,18,20

Answer 1

14)
$x {}^{2} - (a - b)x - ab$

$x {}^{2} - ax + bx - ab$

$x(x - a) + b(x - a)$

$(x + b)(x - a)$


16)
$6ax {}^{3} + 6by + 9bx {}^{2} y + 4ax$

$6ax {}^{3} + 4ax + 6by + 9bx {}^{2} y$

$2ax(3x {}^{2} + 2) + 3by(2 + 3x {}^{2} )$

$(2ax \: + 3by)(3x {}^{2} + 2)$
