Simplifying x2 + 3x + -5(x + -4) = 2x2 + 2x Reorder the terms: x2 + 3x + -5(-4 + x) = 2x2 + 2x x2 + 3x + (-4 * -5 + x * -5) = 2x2 + 2x x2 + 3x + (20 + -5x) = 2x2 + 2x Reorder the terms: 20 + 3x + -5x + x2 = 2x2 + 2x Combine like terms: 3x + -5x = -2x 20 + -2x + x2 = 2x2 + 2x Reorder the terms: 20 + -2x + x2 = 2x + 2x2 Solving 20 + -2x + x2 = 2x + 2x2 Solving for variable 'x'. Reorder the terms: 20 + -2x + -2x + x2 + -2x2 = 2x + 2x2 + -2x + -2x2 Combine like terms: -2x + -2x = -4x 20 + -4x + x2 + -2x2 = 2x + 2x2 + -2x + -2x2 Combine like terms: x2 + -2x2 = -1x2 20 + -4x + -1x2 = 2x + 2x2 + -2x + -2x2 Reorder the terms: 20 + -4x + -1x2 = 2x + -2x + 2x2 + -2x2 Combine like terms: 2x + -2x = 0 20 + -4x + -1x2 = 0 + 2x2 + -2x2 20 + -4x + -1x2 = 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 20 + -4x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -20 + 4x + x2 = 0 Move the constant term to the right: Add '20' to each side of the equation. -20 + 4x + 20 + x2 = 0 + 20 Reorder the terms: -20 + 20 + 4x + x2 = 0 + 20 Combine like terms: -20 + 20 = 0 0 + 4x + x2 = 0 + 20 4x + x2 = 0 + 20 Combine like terms: 0 + 20 = 20 4x + x2 = 20 The x term is 4x. Take half its coefficient (2). Square it (4) and add it to both sides. Add '4' to each side of the equation. 4x + 4 + x2 = 20 + 4 Reorder the terms: 4 + 4x + x2 = 20 + 4 Combine like terms: 20 + 4 = 24 4 + 4x + x2 = 24 Factor a perfect square on the left side: (x + 2)(x + 2) = 24 Calculate the square root of the right side: 4.898979486 Break this problem into two subproblems by setting (x + 2) equal to 4.898979486 and -4.898979486.Subproblem 1
x + 2 = 4.898979486 Simplifying x + 2 = 4.898979486 Reorder the terms: 2 + x = 4.898979486 Solving 2 + x = 4.898979486 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = 4.898979486 + -2 Combine like terms: 2 + -2 = 0 0 + x = 4.898979486 + -2 x = 4.898979486 + -2 Combine like terms: 4.898979486 + -2 = 2.898979486 x = 2.898979486 Simplifying x = 2.898979486Subproblem 2
x + 2 = -4.898979486 Simplifying x + 2 = -4.898979486 Reorder the terms: 2 + x = -4.898979486 Solving 2 + x = -4.898979486 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = -4.898979486 + -2 Combine like terms: 2 + -2 = 0 0 + x = -4.898979486 + -2 x = -4.898979486 + -2 Combine like terms: -4.898979486 + -2 = -6.898979486 x = -6.898979486 Simplifying x = -6.898979486Solution
