Simplifying -4(x) = x2 + -3x + 9 Reorder the terms: -4x = 9 + -3x + x2 Solving -4x = 9 + -3x + x2 Solving for variable 'x'. Reorder the terms: -9 + -4x + 3x + -1x2 = 9 + -3x + x2 + -9 + 3x + -1x2 Combine like terms: -4x + 3x = -1x -9 + -1x + -1x2 = 9 + -3x + x2 + -9 + 3x + -1x2 Reorder the terms: -9 + -1x + -1x2 = 9 + -9 + -3x + 3x + x2 + -1x2 Combine like terms: 9 + -9 = 0 -9 + -1x + -1x2 = 0 + -3x + 3x + x2 + -1x2 -9 + -1x + -1x2 = -3x + 3x + x2 + -1x2 Combine like terms: -3x + 3x = 0 -9 + -1x + -1x2 = 0 + x2 + -1x2 -9 + -1x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 -9 + -1x + -1x2 = 0 Factor out the Greatest Common Factor (GCF), '-1'. -1(9 + x + x2) = 0 Ignore the factor -1.Subproblem 1
Set the factor '(9 + x + x2)' equal to zero and attempt to solve: Simplifying 9 + x + x2 = 0 Solving 9 + x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-9' to each side of the equation. 9 + x + -9 + x2 = 0 + -9 Reorder the terms: 9 + -9 + x + x2 = 0 + -9 Combine like terms: 9 + -9 = 0 0 + x + x2 = 0 + -9 x + x2 = 0 + -9 Combine like terms: 0 + -9 = -9 x + x2 = -9 The x term is x. 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. x + 0.25 + x2 = -9 + 0.25 Reorder the terms: 0.25 + x + x2 = -9 + 0.25 Combine like terms: -9 + 0.25 = -8.75 0.25 + x + x2 = -8.75 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = -8.75 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.
