Solve for the variable:3(2y+7)^ 2=27

  • math -

    Multiply (2y+7)(2y+7)

    It is fine to divide both sides by 3 first, that will make the numbers a little smaller.

    You will have (2y+7)(2y+7) = 27

    After multiplying, you should have 3 terms = 27.

    Subtract the 27 from both sides so that you will have a trinomial = 0. You can then factor to find two different values for x.

    Are you okay from here?
