Question

How do you multiply `(5x + 7)(5x + 6)`?

Answer 1

`25x^2+65x+42`

Explanation:

Use the FOIL technique (first, outside, inside, last)

So by that idea, you would just multiply these pairs:

`5x*5x=25x^2`
`5x*6=30x`
`7*5x=35x`
`7*6=42`

Collect like terms and the answer will be:

= `25x^2+65x+42`
