Simplifying 42 = 15x + -3x2 Solving 42 = 15x + -3x2 Solving for variable 'x'. Reorder the terms: 42 + -15x + 3x2 = 15x + -15x + -3x2 + 3x2 Combine like terms: 15x + -15x = 0 42 + -15x + 3x2 = 0 + -3x2 + 3x2 42 + -15x + 3x2 = -3x2 + 3x2 Combine like terms: -3x2 + 3x2 = 0 42 + -15x + 3x2 = 0 Factor out the Greatest Common Factor (GCF), '3'. 3(14 + -5x + x2) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(14 + -5x + x2)' equal to zero and attempt to solve: Simplifying 14 + -5x + x2 = 0 Solving 14 + -5x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-14' to each side of the equation. 14 + -5x + -14 + x2 = 0 + -14 Reorder the terms: 14 + -14 + -5x + x2 = 0 + -14 Combine like terms: 14 + -14 = 0 0 + -5x + x2 = 0 + -14 -5x + x2 = 0 + -14 Combine like terms: 0 + -14 = -14 -5x + x2 = -14 The x term is -5x. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5x + 6.25 + x2 = -14 + 6.25 Reorder the terms: 6.25 + -5x + x2 = -14 + 6.25 Combine like terms: -14 + 6.25 = -7.75 6.25 + -5x + x2 = -7.75 Factor a perfect square on the left side: (x + -2.5)(x + -2.5) = -7.75 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.
