Question

(x)2 -22x+120 maths.

Answer 1

I think your  question is x ^ 2 - 22 x + 120 and it has to be  factorized.

=  x ^ 2 - 22 x + 120

= x ^ 2 - 10 x - 12 x  + 120

= x ( x - 10 ) - 12 ( x - 10 )

= ( x - 10 ) ( x - 12 ).

Answer 2

${x}^{2} - 12x - 10x + 120 \\ = x |x - 12| - 10 |x - 12| = \\ = |x - 12| |x - 10| \\ = x - 12 = 0 \\ = x = 12 \\ \\ \\ x - 10 = 0 \\ x = 10$
