Rewrite the function by completing the square.
f(x) = x^2 - 12x + 50

For which rational expression is -2 an excluded value of x?

Which of the expressions (on the photo document i inserted) together represent all solutions to the following equation? 8cos(12x)+4=-4 *the answer should be in degrees.* > i would like for someone to explain the process to find the solutions for this.

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.
