Express as a trinomial (3x+7)(x+8)

hey there the answer is:

Step-by-step explanation:

3x(x)+3x(8)  +  7(x)+7(8)

3x^2+24x+7x+56=

56+31x+3x²

3x^2+31x+56

Step-by-step explanation:

First, we need to multiply using the FOIL (first, outer, inner, last) method.

Let's multiply the first terms together:

3x(x)=3x^2

Now we multiply the outer terms:

3x(8)=24x

Next we multiply the inner terms:

7(x)=7x

Finally, we need to multiply the last terms:

7(8)=56

Now we have this:

3x^2+7x+24x+56

Combine like terms:

3x^2+31x+56
