Simplifying 8x2 + -16x + -62 = -9 Reorder the terms: -62 + -16x + 8x2 = -9 Solving -62 + -16x + 8x2 = -9 Solving for variable 'x'. Reorder the terms: -62 + 9 + -16x + 8x2 = -9 + 9 Combine like terms: -62 + 9 = -53 -53 + -16x + 8x2 = -9 + 9 Combine like terms: -9 + 9 = 0 -53 + -16x + 8x2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. -6.625 + -2x + x2 = 0 Move the constant term to the right: Add '6.625' to each side of the equation. -6.625 + -2x + 6.625 + x2 = 0 + 6.625 Reorder the terms: -6.625 + 6.625 + -2x + x2 = 0 + 6.625 Combine like terms: -6.625 + 6.625 = 0.000 0.000 + -2x + x2 = 0 + 6.625 -2x + x2 = 0 + 6.625 Combine like terms: 0 + 6.625 = 6.625 -2x + x2 = 6.625 The x term is -2x. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2x + 1 + x2 = 6.625 + 1 Reorder the terms: 1 + -2x + x2 = 6.625 + 1 Combine like terms: 6.625 + 1 = 7.625 1 + -2x + x2 = 7.625 Factor a perfect square on the left side: (x + -1)(x + -1) = 7.625 Calculate the square root of the right side: 2.761340254 Break this problem into two subproblems by setting (x + -1) equal to 2.761340254 and -2.761340254.Subproblem 1
x + -1 = 2.761340254 Simplifying x + -1 = 2.761340254 Reorder the terms: -1 + x = 2.761340254 Solving -1 + x = 2.761340254 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = 2.761340254 + 1 Combine like terms: -1 + 1 = 0 0 + x = 2.761340254 + 1 x = 2.761340254 + 1 Combine like terms: 2.761340254 + 1 = 3.761340254 x = 3.761340254 Simplifying x = 3.761340254Subproblem 2
x + -1 = -2.761340254 Simplifying x + -1 = -2.761340254 Reorder the terms: -1 + x = -2.761340254 Solving -1 + x = -2.761340254 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = -2.761340254 + 1 Combine like terms: -1 + 1 = 0 0 + x = -2.761340254 + 1 x = -2.761340254 + 1 Combine like terms: -2.761340254 + 1 = -1.761340254 x = -1.761340254 Simplifying x = -1.761340254Solution
