Answer: Option A.


Step-by-step 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 [tex]-5y[/tex].

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   [tex]-5y[/tex].

So, he must obtain the following result:

[tex]20y^{4}-30y^{3}+25y[/tex]




Answer:

A

Step-by-step explanation:

[tex]-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[/tex]
