Ignore the factor 3.

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 '(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.
