Q. Solve the equation by factoring:\newline36x+12x23x3=0 36 x+12 x^{2}-3 x^{3}=0 \newlineAnswer: x= x=
  1. Rearrange Equation: First, we need to rearrange the equation in standard polynomial form, which is usually written from the highest power to the lowest power of xx. So, we rewrite the equation as: 3x3+12x2+36x=0-3x^3 + 12x^2 + 36x = 0
  2. Factor Out GCF: Next, we can factor out the greatest common factor (GCF) from each term. The GCF in this case is 3x3x, so we factor it out:\newline3x(x2+4x+12)=03x(-x^2 + 4x + 12) = 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 12-12 (the constant term) and add up to 44 (the coefficient of the xx term). Those numbers are 66 and 2-2. So, we can write the factored form as: 3x(x6)(x+2)=03x(x - 6)(x + 2) = 0
  4. Set Equations and Solve: To find the solutions, we set each factor equal to zero and solve for xx:3x=03x = 0 or (x6)=0(x - 6) = 0 or (x+2)=0(x + 2) = 0
  5. Find Solutions: Solving each equation for xx gives us the solutions:\newlinex=03x = \frac{0}{3} or x=6x = 6 or x=2x = -2\newlineSimplifying x=03x = \frac{0}{3} gives us x=0x = 0.\newlineSo, the solutions are x=0x = 0, x=6x = 6, and x=2x = -2.
