Set factors equal and solve: Set each factor equal to zero and solve for x.x+6=0 or x−1=0
Check for extraneous solutions: Solve each equation for x.x=−6 or x=1
Check for extraneous solutions: Solve each equation for x.x=−6 or x=1Check for extraneous solutions by plugging the values back into the original equation. For x=−6:−6−2−6+2=−6−3−−84=21, which is not equal to −−63 (which is 21). Therefore, x=−6 is an extraneous solution.
