• Divide both sides by x so that there is only a quadratic equation to be solved.

• Divide both sides by 4 so that the coefficient of the highest term is.

• Factor out an x from the left hand side as a start to factoring the entire left hand side

• Subtract 8x from both sides so that both sides can be factored more readily.
