Equation at the end of step  1  :

((4•(x2))-2x)-((0-5x2)-8x)

Step  2  :

Equation at the end of step  2  :

(22x2 - 2x) - (-5x2 - 8x)

   =9x2 + 6x  =   3x • (3x + 2) 

Final result :

3x • (3x + 2)

Answer 2

Answer:

(4x2-2x)-(-5x2-8x)

=(16x2-2x)-(25x2-8x)

=16x2-2x-25x2+8x {after opening the brackets the signs are changed}

=16x2-25x2-2-8

=-9x2-10
