Q. Solve the equation by factoring:2x3−18x2+16x=0Answer: x=
Factor GCF: Factor out the greatest common factor (GCF) from the given equation.The GCF of 2x3, −18x2, and 16x is 2x. So we factor 2x out of each term.2x(x2−9x+8)=0
Factor Quadratic: Factor the quadratic expression inside the parentheses.We need to find two numbers that multiply to 8 and add up to −9. These numbers are −1 and −8.2x(x−1)(x−8)=0
Solve GCF: Set each factor equal to zero and solve for x.First, set the GCF 2x equal to zero:2x=0x=0
Solve Factor 1: Set the first factor inside the parentheses equal to zero and solve for x.x−1=0x=1
Solve Factor 2: Set the second factor inside the parentheses equal to zero and solve for x.x−8=0x=8
