Simplifying (4x + 3)(x + -8) = 90 Reorder the terms: (3 + 4x)(x + -8) = 90 Reorder the terms: (3 + 4x)(-8 + x) = 90 Multiply (3 + 4x) * (-8 + x) (3(-8 + x) + 4x * (-8 + x)) = 90 ((-8 * 3 + x * 3) + 4x * (-8 + x)) = 90 ((-24 + 3x) + 4x * (-8 + x)) = 90 (-24 + 3x + (-8 * 4x + x * 4x)) = 90 (-24 + 3x + (-32x + 4x2)) = 90 Combine like terms: 3x + -32x = -29x (-24 + -29x + 4x2) = 90 Solving -24 + -29x + 4x2 = 90 Solving for variable 'x'. Reorder the terms: -24 + -90 + -29x + 4x2 = 90 + -90 Combine like terms: -24 + -90 = -114 -114 + -29x + 4x2 = 90 + -90 Combine like terms: 90 + -90 = 0 -114 + -29x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -28.5 + -7.25x + x2 = 0 Move the constant term to the right: Add '28.5' to each side of the equation. -28.5 + -7.25x + 28.5 + x2 = 0 + 28.5 Reorder the terms: -28.5 + 28.5 + -7.25x + x2 = 0 + 28.5 Combine like terms: -28.5 + 28.5 = 0.0 0.0 + -7.25x + x2 = 0 + 28.5 -7.25x + x2 = 0 + 28.5 Combine like terms: 0 + 28.5 = 28.5 -7.25x + x2 = 28.5 The x term is -7.25x. Take half its coefficient (-3.625). Square it (13.140625) and add it to both sides. Add '13.140625' to each side of the equation. -7.25x + 13.140625 + x2 = 28.5 + 13.140625 Reorder the terms: 13.140625 + -7.25x + x2 = 28.5 + 13.140625 Combine like terms: 28.5 + 13.140625 = 41.640625 13.140625 + -7.25x + x2 = 41.640625 Factor a perfect square on the left side: (x + -3.625)(x + -3.625) = 41.640625 Calculate the square root of the right side: 6.45295475 Break this problem into two subproblems by setting (x + -3.625) equal to 6.45295475 and -6.45295475.Subproblem 1
x + -3.625 = 6.45295475 Simplifying x + -3.625 = 6.45295475 Reorder the terms: -3.625 + x = 6.45295475 Solving -3.625 + x = 6.45295475 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3.625' to each side of the equation. -3.625 + 3.625 + x = 6.45295475 + 3.625 Combine like terms: -3.625 + 3.625 = 0.000 0.000 + x = 6.45295475 + 3.625 x = 6.45295475 + 3.625 Combine like terms: 6.45295475 + 3.625 = 10.07795475 x = 10.07795475 Simplifying x = 10.07795475Subproblem 2
x + -3.625 = -6.45295475 Simplifying x + -3.625 = -6.45295475 Reorder the terms: -3.625 + x = -6.45295475 Solving -3.625 + x = -6.45295475 Solving for variable 'x'.
