Answer 1

$\huge \: answer : \\ \\ = {x}^{2} + x - 20 \\ \\ = {x}^{2} - 4x + 5x - 20 \\ \\ = x(x - 4) + 5(x - 4) \\ \\ = (x + 5)(x - 4) \\ \\ other \: \: factor \: \: is \: \: (x - 4)$

Answer 2

Answer:

$ANSWER \:$

$= x {}^{2} + x - 20 \\ = x {}^{2} - 4x + 5x - 20 \\ = x(x - 4 ) + 5(x - 4) \\ = (x + 5) \: (x - 4) \\ other \: factor \: is \: (x - 4)$
