Question

Darryl is finding the product of . Is he correct? If not, what changes should be made?

Answer 1

A

Explanation:

`-5y(-4y^(3) +6y^(2)-5)\\-5y(-4y^(3))-5y(6y^(2))-5y(-5)\\(-5)(-4)y(y^(3))-5(6)y(y^(2))-5(-5)y\\20y^(4)-30y^(3)+25y`

Answer 2

Answer: Option A.

Explanation:

To solve the problem shown in the image attachedl, Darryl must apply a property called Distributive property of multiplication. This means that he must multiply each term inside the parentheses by
`-5y`.

Therefore, by the exponents properties, he should add the exponents of the power with equal base and multiply the signs of each term by the sign of
`-5y`.

So, he must obtain the following result:

`20y^(4)-30y^(3)+25y`
