Solution:

To simplify this expression, multiply the terms together....

(-3x + 5)(2x + 4)
=> (-3x × 2x) + (-3x × 4) + (2x × 5) + (5 × 4)
=> -6x² - 12x + 10x + 20
=> -6x² - 2x + 20

Hence, the simplified expression is -6x² - 2x + 20.

Hoped this helped!

Answer:

$- 6 {x}^{2} -2x + 20$

$( - 3x + 5)(2x + 4) \\ \\ = - 3x(2x + 4) + 5(2x + 4) \\ \\ = - 3x(2x) - 3x(4) + 5(2x) + 5(4) \\ \\ = - 6 {x}^{2} - { 12x} + {10x} + 20 \\ \\ = - 6 {x}^{2}-2x + 20$
