Simplify with steps.

^^

1. (x-1) (5x+8) - 2x+5

2. (-2+5) (3x+9)

3. 2x+5-8x+12

4. (-x+3) (-5x-2)

1. (x-1) (5x+8) - 2x+5

= (x) (5x) + (x) (8) + (-1) (5x) + (-1) (8) + -2x+5

=5x2+8x+-5x+-8+-2x+5

Combine Like Terms:

=5x2+8x+-5x+-8+-2x+5

= (5x2) + (8x+-5x+-2x) + (-8+5)

=5x2 + x + - 3

2. (-2+5) (3x+9)

=9x+27

3. 2x+5-8x+12

=2x+5+-8x+12

Combine Like Terms:

=2x+5+-8x+12

= (2x+-8x) + (5+12)

=-6x+17

4. (-x+3) (-5x-2)

= (-x+3) (-5x+-2)

= (-x) (-5x) + (-x) (-2) + (3) (-5x) + (3) (-2)

=5x2+2x-15x-6

=5x2 - 13x - 6
