Question

Tell me with full solution

Answer 1

=>${x}^{2} + 5x - 36 = 0$

=>$now \: find \: the \: factor \: of \: 36 \: whose \ \: sum \: \: is \: 5$
$the \: factors \: are \: 9 \times ( - 4)$

=>${x}^{2} + 9x - 4x - 36 = 0$

=>$taking \: common \: multiple \:$

=>$x(x + 9) - 4(x + 9) = 0$

=>$(x + 9)(x - 4) = 0$

=>$x + 9 = 0 \: \: \: and \: x - 4 = 0$

=>$x = - 9 \: \: \: and \: x = 4 \: is \: the \: solution$
