Q. Solve the equation by factoring:2x3+12x2−32x=0Answer: x=
Factor GCF: First, we need to factor out the greatest common factor (GCF) from the given equation 2x3+12x2−32x=0. The GCF is 2x, so we factor it out from each term. 2x(x2+6x−16)=0
Factor Quadratic Expression: Next, we need to factor the quadratic expression x2+6x−16. We look for two numbers that multiply to −16 and add up to 6. These numbers are 8 and −2. So, we can write the quadratic as (x+8)(x−2).
Final Factored Form: Now, we have the factored form of the equation: 2x(x+8)(x−2)=0
Solve for x (1): To find the values of x, we set each factor equal to zero and solve for x. First, set 2x=0, which gives us x=0.
Solve for x (2): Next, set (x+8)=0, which gives us x=−8.
Solve for x (3): Finally, set (x−2)=0, which gives us x=2.
