Question

solve the following equation by factorization method .x +x - 20= 0​

Answer 1

x=-20

or

x=-1

i think so

Answer 2

$x + x - 20 = 0 \\ 2x - 20 = 0 \\2 x = 20 \\ x = \frac{20}{2} \\ x = 10 \\ or \\ x + x - 20 = 0 \\ 2x - 20 = 0 \\ 2(x - 10) = 0 \\ since \: this \: polynomial \: has \: highest \: degree \\ 1 \: so \: it \: has \: factor \: as \\ 2 \: and \: (x - 10)$
