Q. Solve the equation by factoring:16x2−30x−2x3=0Answer: x=
Rewrite in Standard Form: First, let's rewrite the equation in standard form by arranging the terms in descending order of their exponents.The given equation is 16x2−30x−2x3=0.Rearrange the terms to get −2x3+16x2−30x=0.
Factor Out Common Factor: Next, factor out the greatest common factor, which in this case is −2x. So, −2x(x2−8x+15)=0.
Factor Quadratic Expression: Now, we need to factor the quadratic expression x2−8x+15. To find factors of 15 that add up to −8, we can use −3 and −5. So, x2−8x+15 can be factored as (x−3)(x−5).
Find Roots: The factored form of the original equation is now −2x(x−3)(x−5)=0. To find the roots, we set each factor equal to zero and solve for x. −2x=0, x−3=0, and x−5=0.
Find Roots: The factored form of the original equation is now −2x(x−3)(x−5)=0.To find the roots, we set each factor equal to zero and solve for x.−2x=0, x−3=0, and x−5=0.Solving each equation for x gives us the roots:From −2x=0, we get x=0.From x−3=0, we get x=3.From x−5=0, we get x1.
