9th grade algebra/Ms Sue

posted by .

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.

  • 9th grade algebra/Ms Sue -

    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
