Simplifying 0 = 2x2 + 20x + -144 Reorder the terms: 0 = -144 + 20x + 2x2 Solving 0 = -144 + 20x + 2x2 Solving for variable 'x'. Combine like terms: 0 + 144 = 144 144 + -20x + -2x2 = -144 + 20x + 2x2 + 144 + -20x + -2x2 Reorder the terms: 144 + -20x + -2x2 = -144 + 144 + 20x + -20x + 2x2 + -2x2 Combine like terms: -144 + 144 = 0 144 + -20x + -2x2 = 0 + 20x + -20x + 2x2 + -2x2 144 + -20x + -2x2 = 20x + -20x + 2x2 + -2x2 Combine like terms: 20x + -20x = 0 144 + -20x + -2x2 = 0 + 2x2 + -2x2 144 + -20x + -2x2 = 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 144 + -20x + -2x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(72 + -10x + -1x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(72 + -10x + -1x2)' equal to zero and attempt to solve: Simplifying 72 + -10x + -1x2 = 0 Solving 72 + -10x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -72 + 10x + x2 = 0 Move the constant term to the right: Add '72' to each side of the equation. -72 + 10x + 72 + x2 = 0 + 72 Reorder the terms: -72 + 72 + 10x + x2 = 0 + 72 Combine like terms: -72 + 72 = 0 0 + 10x + x2 = 0 + 72 10x + x2 = 0 + 72 Combine like terms: 0 + 72 = 72 10x + x2 = 72 The x term is 10x. Take half its coefficient (5). Square it (25) and add it to both sides. Add '25' to each side of the equation. 10x + 25 + x2 = 72 + 25 Reorder the terms: 25 + 10x + x2 = 72 + 25 Combine like terms: 72 + 25 = 97 25 + 10x + x2 = 97 Factor a perfect square on the left side: (x + 5)(x + 5) = 97 Calculate the square root of the right side: 9.848857802 Break this problem into two subproblems by setting (x + 5) equal to 9.848857802 and -9.848857802.Subproblem 1
x + 5 = 9.848857802 Simplifying x + 5 = 9.848857802 Reorder the terms: 5 + x = 9.848857802 Solving 5 + x = 9.848857802 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + x = 9.848857802 + -5 Combine like terms: 5 + -5 = 0 0 + x = 9.848857802 + -5 x = 9.848857802 + -5 Combine like terms: 9.848857802 + -5 = 4.848857802 x = 4.848857802 Simplifying x = 4.848857802Subproblem 2
x + 5 = -9.848857802 Simplifying x + 5 = -9.848857802 Reorder the terms: 5 + x = -9.848857802 Solving 5 + x = -9.848857802 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + x = -9.848857802 + -5 Combine like terms: 5 + -5 = 0 0 + x = -9.848857802 + -5 x = -9.848857802 + -5 Combine like terms: -9.848857802 + -5 = -14.848857802 x = -14.848857802 Simplifying x = -14.848857802Solution
