Simplifying 3x2 = 3x + -90 Reorder the terms: 3x2 = -90 + 3x Solving 3x2 = -90 + 3x Solving for variable 'x'. Reorder the terms: 90 + -3x + 3x2 = -90 + 3x + 90 + -3x Reorder the terms: 90 + -3x + 3x2 = -90 + 90 + 3x + -3x Combine like terms: -90 + 90 = 0 90 + -3x + 3x2 = 0 + 3x + -3x 90 + -3x + 3x2 = 3x + -3x Combine like terms: 3x + -3x = 0 90 + -3x + 3x2 = 0 Factor out the Greatest Common Factor (GCF), '3'. 3(30 + -1x + x2) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(30 + -1x + x2)' equal to zero and attempt to solve: Simplifying 30 + -1x + x2 = 0 Solving 30 + -1x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-30' to each side of the equation. 30 + -1x + -30 + x2 = 0 + -30 Reorder the terms: 30 + -30 + -1x + x2 = 0 + -30 Combine like terms: 30 + -30 = 0 0 + -1x + x2 = 0 + -30 -1x + x2 = 0 + -30 Combine like terms: 0 + -30 = -30 -1x + x2 = -30 The x term is -1x. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1x + 0.25 + x2 = -30 + 0.25 Reorder the terms: 0.25 + -1x + x2 = -30 + 0.25 Combine like terms: -30 + 0.25 = -29.75 0.25 + -1x + x2 = -29.75 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = -29.75 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.
