Math! Ms.Sue Please

Evaluate: l-x^2l (x - y) + (x^3 + y) If x + 8 = 3 and y = 3_
\l 8
Is the answer -202? I did it in the calculator but forgot how to work it out

asked by Sarah
  1. l -(-5)^2 l [( -5) - (-2)] + [(-5)^3 + (-2)]
    Ms.Sue i broke it down more! Hopefully that helps

  2. just plug in the values x = -5 and y = 3

    l-x^2l (x - y) + (x^3 + y)
    = |-25| (-5-3) + (-125+3)
    = 25(-8) + (-122)
    = -322
