Simplifying -5x(4x + 6) = 21 Reorder the terms: -5x(6 + 4x) = 21 (6 * -5x + 4x * -5x) = 21 (-30x + -20x2) = 21 Solving -30x + -20x2 = 21 Solving for variable 'x'. Reorder the terms: -21 + -30x + -20x2 = 21 + -21 Combine like terms: 21 + -21 = 0 -21 + -30x + -20x2 = 0 Factor out the Greatest Common Factor (GCF), '-1'. -1(21 + 30x + 20x2) = 0 Ignore the factor -1.Subproblem 1
Set the factor '(21 + 30x + 20x2)' equal to zero and attempt to solve: Simplifying 21 + 30x + 20x2 = 0 Solving 21 + 30x + 20x2 = 0 Begin completing the square. Divide all terms by 20 the coefficient of the squared term: Divide each side by '20'. 1.05 + 1.5x + x2 = 0.0 Move the constant term to the right: Add '-1.05' to each side of the equation. 1.05 + 1.5x + -1.05 + x2 = 0.0 + -1.05 Reorder the terms: 1.05 + -1.05 + 1.5x + x2 = 0.0 + -1.05 Combine like terms: 1.05 + -1.05 = 0.00 0.00 + 1.5x + x2 = 0.0 + -1.05 1.5x + x2 = 0.0 + -1.05 Combine like terms: 0.0 + -1.05 = -1.05 1.5x + x2 = -1.05 The x term is 1.5x. Take half its coefficient (0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. 1.5x + 0.5625 + x2 = -1.05 + 0.5625 Reorder the terms: 0.5625 + 1.5x + x2 = -1.05 + 0.5625 Combine like terms: -1.05 + 0.5625 = -0.4875 0.5625 + 1.5x + x2 = -0.4875 Factor a perfect square on the left side: (x + 0.75)(x + 0.75) = -0.4875 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
