Answer:

(5y-2)(2y²+3y-4)

=(5y)(2y²) + (5y)(3y) + (5y)(-4) + (-2)(2y²) + (-2)(3y) + (-2)(-4)

=10y³ + 15y² - 20y - 4y² - 6y + 8

=10y³ + 15y² - 4y² - 20y - 6y + 8

=10y³ + 11y² - 26y + 8

Step-by-step explanation:

Use the distributive property in order to solve and get the final answer..

Hope it helps..

The solution and the answer is in the picture.

I used the FOIL method,because it easier to understand than the other methods.
