Question

Factorise x^2+ 8 x − 33

Answer 1

$\huge {\green {\underline {\underline {\mathfrak {Answer}}}}}$

${x}^{2} + 8x - 33 = 0 \\ = > {x}^{2} + 11x - 3x - 33 = 0 \\ = > x(x + 11) - 3(x + 11) = 0 \\ = > (x - 3)(x + 11) = 0 \\ = > x = 3 \: or \: - 11$

Answer 2

$x ^{2} + 8x - 33 \\ = > x ^{2} + 11x - 3x - 33 \\ on \: taking \: common \\ = > x(x + 11) - 3(x + 11) \\ = > (x + 11)(x - 3)$
