Answer 2

Answer:

this question has difect because:

x²+7x+120

x²+(15-8) x+120

=x²+15x -8 x +120

= x²-8x+15x+120

=x(x-8) -15(x

if x²+70x +120 is there 120 should be 1200 then 40 × 30 = 1200

40+30= 70

Step-by-step explanation:

120=1x 120

= 2x 60

=3x40

=4x30

=5x24

=6x 20

=8× 15 here 15- 8= 7
