Q. Solve the equation by factoring:x3−2x2−48x=0Answer: x=
Factor GCF: Factor out the greatest common factor (GCF) from the equation x3−2x2−48x=0. The GCF is x, so we factor it out to get x(x2−2x−48)=0.
Factor Quadratic: Factor the quadratic equationx2−2x−48. We look for two numbers that multiply to −48 and add up to −2. These numbers are −8 and +6. So, we can write the quadratic as (x−8)(x+6).
Write Factored Form: Write the factored form of the original equation using the factors found in Step 2.The factored form is x(x−8)(x+6)=0.
Solve for x: Set each factor equal to zero and solve for x.First factor: x=0Second factor: x−8=0, which gives x=8Third factor: x+6=0, which gives x=−6
Find Roots: Write down all the roots of the equation.The roots are x=0, x=8, and x=−6.
