Simplifying 3x3 + 120x2 = 1200x Reorder the terms: 120x2 + 3x3 = 1200x Solving 120x2 + 3x3 = 1200x Solving for variable 'x'. Reorder the terms: -1200x + 120x2 + 3x3 = 1200x + -1200x Combine like terms: 1200x + -1200x = 0 -1200x + 120x2 + 3x3 = 0 Factor out the Greatest Common Factor (GCF), '3x'. 3x(-400 + 40x + x2) = 0 Ignore the factor 3.Subproblem 1
Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0Subproblem 2
Set the factor '(-400 + 40x + x2)' equal to zero and attempt to solve: Simplifying -400 + 40x + x2 = 0 Solving -400 + 40x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '400' to each side of the equation. -400 + 40x + 400 + x2 = 0 + 400 Reorder the terms: -400 + 400 + 40x + x2 = 0 + 400 Combine like terms: -400 + 400 = 0 0 + 40x + x2 = 0 + 400 40x + x2 = 0 + 400 Combine like terms: 0 + 400 = 400 40x + x2 = 400 The x term is 40x. Take half its coefficient (20). Square it (400) and add it to both sides. Add '400' to each side of the equation. 40x + 400 + x2 = 400 + 400 Reorder the terms: 400 + 40x + x2 = 400 + 400 Combine like terms: 400 + 400 = 800 400 + 40x + x2 = 800 Factor a perfect square on the left side: (x + 20)(x + 20) = 800 Calculate the square root of the right side: 28.284271247 Break this problem into two subproblems by setting (x + 20) equal to 28.284271247 and -28.284271247.Subproblem 1
x + 20 = 28.284271247 Simplifying x + 20 = 28.284271247 Reorder the terms: 20 + x = 28.284271247 Solving 20 + x = 28.284271247 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-20' to each side of the equation. 20 + -20 + x = 28.284271247 + -20 Combine like terms: 20 + -20 = 0 0 + x = 28.284271247 + -20 x = 28.284271247 + -20 Combine like terms: 28.284271247 + -20 = 8.284271247 x = 8.284271247 Simplifying x = 8.284271247Subproblem 2
x + 20 = -28.284271247 Simplifying x + 20 = -28.284271247 Reorder the terms: 20 + x = -28.284271247 Solving 20 + x = -28.284271247 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-20' to each side of the equation. 20 + -20 + x = -28.284271247 + -20 Combine like terms: 20 + -20 = 0 0 + x = -28.284271247 + -20 x = -28.284271247 + -20 Combine like terms: -28.284271247 + -20 = -48.284271247 x = -48.284271247 Simplifying x = -48.284271247Solution
