Subproblem 1

Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0

Subproblem 2

Set the factor '(12 + -1x + 8x2)' equal to zero and attempt to solve: Simplifying 12 + -1x + 8x2 = 0 Solving 12 + -1x + 8x2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 1.5 + -0.125x + x2 = 0 Move the constant term to the right: Add '-1.5' to each side of the equation. 1.5 + -0.125x + -1.5 + x2 = 0 + -1.5 Reorder the terms: 1.5 + -1.5 + -0.125x + x2 = 0 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + -0.125x + x2 = 0 + -1.5 -0.125x + x2 = 0 + -1.5 Combine like terms: 0 + -1.5 = -1.5 -0.125x + x2 = -1.5 The x term is -0.125x. Take half its coefficient (-0.0625). Square it (0.00390625) and add it to both sides. Add '0.00390625' to each side of the equation. -0.125x + 0.00390625 + x2 = -1.5 + 0.00390625 Reorder the terms: 0.00390625 + -0.125x + x2 = -1.5 + 0.00390625 Combine like terms: -1.5 + 0.00390625 = -1.49609375 0.00390625 + -0.125x + x2 = -1.49609375 Factor a perfect square on the left side: (x + -0.0625)(x + -0.0625) = -1.49609375 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.
