Q. Solve the equation by factoring:\newline36x2160x2x3=0 36 x^{2}-160 x-2 x^{3}=0 \newlineAnswer: x= x=
  1. Rewrite in Standard Form: First, let's rewrite the equation in standard form by arranging the terms in descending order of their exponents.\newlineThe given equation is 36x2160x2x3=036x^2 - 160x - 2x^3 = 0.\newlineRearrange the terms to get 2x3+36x2160x=0-2x^3 + 36x^2 - 160x = 0.
  2. Factor Out GCF: Next, we factor out the greatest common factor (GCF) from all the terms. The GCF in this case is 2x-2x. So, we factor 2x-2x out of each term to get 2x(x218x+80)=0-2x(x^2 - 18x + 80) = 0.
  3. Factor Quadratic Expression: Now, we need to factor the quadratic expression inside the parentheses. We are looking for two numbers that multiply to 8080 and add up to 18-18. The numbers that satisfy these conditions are 10-10 and 8-8. So, we can write the quadratic as (x10)(x8)(x - 10)(x - 8).
  4. Find Roots: The factored form of the equation is now 2x(x10)(x8)=0-2x(x - 10)(x - 8) = 0. To find the roots, we set each factor equal to zero and solve for xx.
  5. First Factor: Setting the first factor equal to zero gives us 2x=0-2x = 0, which means x=0x = 0.
  6. Second Factor: Setting the second factor equal to zero gives us x10=0x - 10 = 0, which means x=10x = 10.
  7. Third Factor: Setting the third factor equal to zero gives us x8=0x - 8 = 0, which means x=8x = 8.
