Question

Evaluate (a+7) * (a²+3a+5)

Answer 1

Answer:a^3+10a^2+26a+35

Step-by-step explanation:

(a+7) * (a^2+3a+5)

First multiply (a^2+3a+5) by a and then by 7. And add them.

(a^3+3a^2+5a)+(7a^2+21a+35)

a^3+10a^2+26a+35

Answer 2

Given,

• (a+7) * (a²+3a+5) is given.

To find,

• We have to evaluate the given expression.

Solution,

We can simply evaluate the given expression by using the distributive law.

          (a+7) * (a²+3a+5)

Using distributive law, we get

           a(a²+3a+5)+7(a²+3a+5)

            a³+3a²+5a+7a²+21a+35

Now, simplyfying the like terms, we get

           a³+10a²+26a+35

Hence, the given expression (a+7) * (a²+3a+5) can be evaluated as a³+10a²+26a+35.
