Evaluate the following expressions for x=-3

13)–2x^2 =
14)(-2x)^2 =

10)Use the discriminant to determine
the number of solutions of 3x^2-4x+6=0
8)Solve sqrt[3b] = -3

  • math -

    13) 12
    14) 36
    10) ?
    8)b=-2
    just square both sides to get rid of the sqrt and divide both sides by 3 and you get -2
