I'll do the first one to get you started.

# 1

or Start with the given solutions.

or Get everything to one side so that only 0 remains on the right side (for both equations).

Use the zero product property to combine the equations.

FOIL out the left side.

So the answer is

To check your work, simply solve for x. Doing so will show you that the solutions are or , which confirm the answer.
