5-26.
  1. Solve the following equations for the given variable, if possible. Remember to check your answers. Homework Help ✎

    1. 6x2 = 150

    2. 4m + 3 − m = 3(m + 1)

    3. (k − 4)2 = −3

Isolate the x². There are two solutions to this equation.

All numbers, because the expressions on both sides are the same 3m + 3 = 3m + 3

Start by squaring both sides.

No real numbers, because any number squared is a positive number, so (k − 4)² ≠ −3.
