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 '(-2 + 3x + -5x2)' equal to zero and attempt to solve: Simplifying -2 + 3x + -5x2 = 0 Solving -2 + 3x + -5x2 = 0 Begin completing the square. Divide all terms by -5 the coefficient of the squared term: Divide each side by '-5'. 0.4 + -0.6x + x2 = 0 Move the constant term to the right: Add '-0.4' to each side of the equation. 0.4 + -0.6x + -0.4 + x2 = 0 + -0.4 Reorder the terms: 0.4 + -0.4 + -0.6x + x2 = 0 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + -0.6x + x2 = 0 + -0.4 -0.6x + x2 = 0 + -0.4 Combine like terms: 0 + -0.4 = -0.4 -0.6x + x2 = -0.4 The x term is -0.6x. Take half its coefficient (-0.3). Square it (0.09) and add it to both sides. Add '0.09' to each side of the equation. -0.6x + 0.09 + x2 = -0.4 + 0.09 Reorder the terms: 0.09 + -0.6x + x2 = -0.4 + 0.09 Combine like terms: -0.4 + 0.09 = -0.31 0.09 + -0.6x + x2 = -0.31 Factor a perfect square on the left side: (x + -0.3)(x + -0.3) = -0.31 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.
