Okay Ms. Sue. I am in 8th grade but I am taking Algebra with 9th graders. I am very confused with my previous problem. I have asked my Dad but we are both getting confused. Now I have come up with 22. Is this my correct answer?

I think my previous answer was right. But check with your teacher tomorrow.

3x^2 - 5x

when x=-2 we get

3(-2)^2 - 5(-2)

= 3(4) + 10

= 12 + 10

= 22

Ms Sue read the question as

(3x)^2 - 5x

You originally typed in "words" without brackets as

"3x squared ..... " , which when sounded out becomes 3x^2
