Simplifying (x + 9)(5x + -3) = 18 Reorder the terms: (9 + x)(5x + -3) = 18 Reorder the terms: (9 + x)(-3 + 5x) = 18 Multiply (9 + x) * (-3 + 5x) (9(-3 + 5x) + x(-3 + 5x)) = 18 ((-3 * 9 + 5x * 9) + x(-3 + 5x)) = 18 ((-27 + 45x) + x(-3 + 5x)) = 18 (-27 + 45x + (-3 * x + 5x * x)) = 18 (-27 + 45x + (-3x + 5x2)) = 18 Combine like terms: 45x + -3x = 42x (-27 + 42x + 5x2) = 18 Solving -27 + 42x + 5x2 = 18 Solving for variable 'x'. Reorder the terms: -27 + -18 + 42x + 5x2 = 18 + -18 Combine like terms: -27 + -18 = -45 -45 + 42x + 5x2 = 18 + -18 Combine like terms: 18 + -18 = 0 -45 + 42x + 5x2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -9 + 8.4x + x2 = 0 Move the constant term to the right: Add '9' to each side of the equation. -9 + 8.4x + 9 + x2 = 0 + 9 Reorder the terms: -9 + 9 + 8.4x + x2 = 0 + 9 Combine like terms: -9 + 9 = 0 0 + 8.4x + x2 = 0 + 9 8.4x + x2 = 0 + 9 Combine like terms: 0 + 9 = 9 8.4x + x2 = 9 The x term is 8.4x. Take half its coefficient (4.2). Square it (17.64) and add it to both sides. Add '17.64' to each side of the equation. 8.4x + 17.64 + x2 = 9 + 17.64 Reorder the terms: 17.64 + 8.4x + x2 = 9 + 17.64 Combine like terms: 9 + 17.64 = 26.64 17.64 + 8.4x + x2 = 26.64 Factor a perfect square on the left side: (x + 4.2)(x + 4.2) = 26.64 Calculate the square root of the right side: 5.16139516 Break this problem into two subproblems by setting (x + 4.2) equal to 5.16139516 and -5.16139516.Subproblem 1
x + 4.2 = 5.16139516 Simplifying x + 4.2 = 5.16139516 Reorder the terms: 4.2 + x = 5.16139516 Solving 4.2 + x = 5.16139516 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.2' to each side of the equation. 4.2 + -4.2 + x = 5.16139516 + -4.2 Combine like terms: 4.2 + -4.2 = 0.0 0.0 + x = 5.16139516 + -4.2 x = 5.16139516 + -4.2 Combine like terms: 5.16139516 + -4.2 = 0.96139516 x = 0.96139516 Simplifying x = 0.96139516Subproblem 2
x + 4.2 = -5.16139516 Simplifying x + 4.2 = -5.16139516 Reorder the terms: 4.2 + x = -5.16139516 Solving 4.2 + x = -5.16139516 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.2' to each side of the equation. 4.2 + -4.2 + x = -5.16139516 + -4.2 Combine like terms: 4.2 + -4.2 = 0.0 0.0 + x = -5.16139516 + -4.2 x = -5.16139516 + -4.2 Combine like terms: -5.16139516 + -4.2 = -9.36139516 x = -9.36139516 Simplifying x = -9.36139516Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.96139516, -9.36139516}
