Q. Solve the equation by factoring:x3−12x2+32x=0Answer: x=
Identify common factor: Identify the common factor in the equation x3−12x2+32x=0. All terms have an x in common, so factor out x. x(x2−12x+32)=0
Factor quadratic equation: Now we have a quadratic equation to factor: x2−12x+32. We need to find two numbers that multiply to 32 and add up to −12. The numbers −4 and −8 satisfy these conditions. So, we can factor the quadratic as (x−4)(x−8). x(x−4)(x−8)=0
Solve for x: Set each factor equal to zero and solve for x.First factor: x=0Second factor: x−4=0, so x=4Third factor: x−8=0, so x=8
