Factor the polynomial completely.x5 – 7×4 – 18×3

Factor the trinomial.x2 + x – 42

Factor out the greatest common factor.12(y + 13) – x(y + 13)

Find the function.If P(x) = x – 8 and Q(x) = x2 – 11, find P(x) ∙ Q(x).

Solve the equation by completing the square.8×2 + 1 = 5x

Multiply.(8y + x)(8y – x)

Solve.If Jon can paint the fence in 2 hours and Karen can paint it in 5 hours, find how long it takes them to paint it together.

Solve.Find the volume of the box.

Use the quadratic formula to solve the equation.x(x + 6) = 6
