Simplifying 4x(5x + -3) = 84 Reorder the terms: 4x(-3 + 5x) = 84 (-3 * 4x + 5x * 4x) = 84 (-12x + 20x2) = 84 Solving -12x + 20x2 = 84 Solving for variable 'x'. Reorder the terms: -84 + -12x + 20x2 = 84 + -84 Combine like terms: 84 + -84 = 0 -84 + -12x + 20x2 = 0 Factor out the Greatest Common Factor (GCF), '4'. 4(-21 + -3x + 5x2) = 0 Ignore the factor 4.Subproblem 1
Set the factor '(-21 + -3x + 5x2)' equal to zero and attempt to solve: Simplifying -21 + -3x + 5x2 = 0 Solving -21 + -3x + 5x2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -4.2 + -0.6x + x2 = 0 Move the constant term to the right: Add '4.2' to each side of the equation. -4.2 + -0.6x + 4.2 + x2 = 0 + 4.2 Reorder the terms: -4.2 + 4.2 + -0.6x + x2 = 0 + 4.2 Combine like terms: -4.2 + 4.2 = 0.0 0.0 + -0.6x + x2 = 0 + 4.2 -0.6x + x2 = 0 + 4.2 Combine like terms: 0 + 4.2 = 4.2 -0.6x + x2 = 4.2 The x term is -0.6x. Take half its coefficient (-0.3). Square it (0.09) and add it to both sides. Add '0.09' to each side of the equation. -0.6x + 0.09 + x2 = 4.2 + 0.09 Reorder the terms: 0.09 + -0.6x + x2 = 4.2 + 0.09 Combine like terms: 4.2 + 0.09 = 4.29 0.09 + -0.6x + x2 = 4.29 Factor a perfect square on the left side: (x + -0.3)(x + -0.3) = 4.29 Calculate the square root of the right side: 2.071231518 Break this problem into two subproblems by setting (x + -0.3) equal to 2.071231518 and -2.071231518.Subproblem 1
x + -0.3 = 2.071231518 Simplifying x + -0.3 = 2.071231518 Reorder the terms: -0.3 + x = 2.071231518 Solving -0.3 + x = 2.071231518 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.3' to each side of the equation. -0.3 + 0.3 + x = 2.071231518 + 0.3 Combine like terms: -0.3 + 0.3 = 0.0 0.0 + x = 2.071231518 + 0.3 x = 2.071231518 + 0.3 Combine like terms: 2.071231518 + 0.3 = 2.371231518 x = 2.371231518 Simplifying x = 2.371231518Subproblem 2
x + -0.3 = -2.071231518 Simplifying x + -0.3 = -2.071231518 Reorder the terms: -0.3 + x = -2.071231518 Solving -0.3 + x = -2.071231518 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.3' to each side of the equation. -0.3 + 0.3 + x = -2.071231518 + 0.3 Combine like terms: -0.3 + 0.3 = 0.0 0.0 + x = -2.071231518 + 0.3 x = -2.071231518 + 0.3 Combine like terms: -2.071231518 + 0.3 = -1.771231518 x = -1.771231518 Simplifying x = -1.771231518Solution
