Answer 1

Answer:

• Solution:

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

Solution:(4x2 - 2x) - (-5x2 - 8x)= 4x2 - 2x + 5x2 + 8x.

Solution:(4x2 - 2x) - (-5x2 - 8x)= 4x2 - 2x + 5x2 + 8x.= 4x2 + 5x2 - 2x + 8x.

Solution:(4x2 - 2x) - (-5x2 - 8x)= 4x2 - 2x + 5x2 + 8x.= 4x2 + 5x2 - 2x + 8x.= 9x2 + 6x.

Solution:(4x2 - 2x) - (-5x2 - 8x)= 4x2 - 2x + 5x2 + 8x.= 4x2 + 5x2 - 2x + 8x.= 9x2 + 6x.= 3x(3x + 2).
