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 '(-18 + -3x + 2x2)' equal to zero and attempt to solve: Simplifying -18 + -3x + 2x2 = 0 Solving -18 + -3x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -9 + -1.5x + x2 = 0 Move the constant term to the right: Add '9' to each side of the equation. -9 + -1.5x + 9 + x2 = 0 + 9 Reorder the terms: -9 + 9 + -1.5x + x2 = 0 + 9 Combine like terms: -9 + 9 = 0 0 + -1.5x + x2 = 0 + 9 -1.5x + x2 = 0 + 9 Combine like terms: 0 + 9 = 9 -1.5x + x2 = 9 The x term is -1.5x. Take half its coefficient (-0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. -1.5x + 0.5625 + x2 = 9 + 0.5625 Reorder the terms: 0.5625 + -1.5x + x2 = 9 + 0.5625 Combine like terms: 9 + 0.5625 = 9.5625 0.5625 + -1.5x + x2 = 9.5625 Factor a perfect square on the left side: (x + -0.75)(x + -0.75) = 9.5625 Calculate the square root of the right side: 3.092329219 Break this problem into two subproblems by setting (x + -0.75) equal to 3.092329219 and -3.092329219.

Subproblem 1

x + -0.75 = 3.092329219 Simplifying x + -0.75 = 3.092329219 Reorder the terms: -0.75 + x = 3.092329219 Solving -0.75 + x = 3.092329219 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + x = 3.092329219 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + x = 3.092329219 + 0.75 x = 3.092329219 + 0.75 Combine like terms: 3.092329219 + 0.75 = 3.842329219 x = 3.842329219 Simplifying x = 3.842329219

Subproblem 2

x + -0.75 = -3.092329219 Simplifying x + -0.75 = -3.092329219 Reorder the terms: -0.75 + x = -3.092329219 Solving -0.75 + x = -3.092329219 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + x = -3.092329219 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + x = -3.092329219 + 0.75 x = -3.092329219 + 0.75 Combine like terms: -3.092329219 + 0.75 = -2.342329219 x = -2.342329219 Simplifying x = -2.342329219
