Simplifying (8x + -3)(8x + -3) = 30 Reorder the terms: (-3 + 8x)(8x + -3) = 30 Reorder the terms: (-3 + 8x)(-3 + 8x) = 30 Multiply (-3 + 8x) * (-3 + 8x) (-3(-3 + 8x) + 8x * (-3 + 8x)) = 30 ((-3 * -3 + 8x * -3) + 8x * (-3 + 8x)) = 30 ((9 + -24x) + 8x * (-3 + 8x)) = 30 (9 + -24x + (-3 * 8x + 8x * 8x)) = 30 (9 + -24x + (-24x + 64x2)) = 30 Combine like terms: -24x + -24x = -48x (9 + -48x + 64x2) = 30 Solving 9 + -48x + 64x2 = 30 Solving for variable 'x'. Reorder the terms: 9 + -30 + -48x + 64x2 = 30 + -30 Combine like terms: 9 + -30 = -21 -21 + -48x + 64x2 = 30 + -30 Combine like terms: 30 + -30 = 0 -21 + -48x + 64x2 = 0 Begin completing the square. Divide all terms by 64 the coefficient of the squared term: Divide each side by '64'. -0.328125 + -0.75x + x2 = 0 Move the constant term to the right: Add '0.328125' to each side of the equation. -0.328125 + -0.75x + 0.328125 + x2 = 0 + 0.328125 Reorder the terms: -0.328125 + 0.328125 + -0.75x + x2 = 0 + 0.328125 Combine like terms: -0.328125 + 0.328125 = 0.000000 0.000000 + -0.75x + x2 = 0 + 0.328125 -0.75x + x2 = 0 + 0.328125 Combine like terms: 0 + 0.328125 = 0.328125 -0.75x + x2 = 0.328125 The x term is -0.75x. Take half its coefficient (-0.375). Square it (0.140625) and add it to both sides. Add '0.140625' to each side of the equation. -0.75x + 0.140625 + x2 = 0.328125 + 0.140625 Reorder the terms: 0.140625 + -0.75x + x2 = 0.328125 + 0.140625 Combine like terms: 0.328125 + 0.140625 = 0.46875 0.140625 + -0.75x + x2 = 0.46875 Factor a perfect square on the left side: (x + -0.375)(x + -0.375) = 0.46875 Calculate the square root of the right side: 0.684653197 Break this problem into two subproblems by setting (x + -0.375) equal to 0.684653197 and -0.684653197.Subproblem 1
x + -0.375 = 0.684653197 Simplifying x + -0.375 = 0.684653197 Reorder the terms: -0.375 + x = 0.684653197 Solving -0.375 + x = 0.684653197 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.375' to each side of the equation. -0.375 + 0.375 + x = 0.684653197 + 0.375 Combine like terms: -0.375 + 0.375 = 0.000 0.000 + x = 0.684653197 + 0.375 x = 0.684653197 + 0.375 Combine like terms: 0.684653197 + 0.375 = 1.059653197 x = 1.059653197 Simplifying x = 1.059653197Subproblem 2
x + -0.375 = -0.684653197 Simplifying x + -0.375 = -0.684653197 Reorder the terms: -0.375 + x = -0.684653197 Solving -0.375 + x = -0.684653197 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.375' to each side of the equation. -0.375 + 0.375 + x = -0.684653197 + 0.375 Combine like terms: -0.375 + 0.375 = 0.000 0.000 + x = -0.684653197 + 0.375 x = -0.684653197 + 0.375 Combine like terms: -0.684653197 + 0.375 = -0.309653197 x = -0.309653197 Simplifying x = -0.309653197Solution
