Simplifying 15 = 40x + -1x2 Solving 15 = 40x + -1x2 Solving for variable 'x'. Reorder the terms: 15 + -40x + x2 = 40x + -40x + -1x2 + x2 Combine like terms: 40x + -40x = 0 15 + -40x + x2 = 0 + -1x2 + x2 15 + -40x + x2 = -1x2 + x2 Combine like terms: -1x2 + x2 = 0 15 + -40x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-15' to each side of the equation. 15 + -40x + -15 + x2 = 0 + -15 Reorder the terms: 15 + -15 + -40x + x2 = 0 + -15 Combine like terms: 15 + -15 = 0 0 + -40x + x2 = 0 + -15 -40x + x2 = 0 + -15 Combine like terms: 0 + -15 = -15 -40x + x2 = -15 The x term is -40x. Take half its coefficient (-20). Square it (400) and add it to both sides. Add '400' to each side of the equation. -40x + 400 + x2 = -15 + 400 Reorder the terms: 400 + -40x + x2 = -15 + 400 Combine like terms: -15 + 400 = 385 400 + -40x + x2 = 385 Factor a perfect square on the left side: (x + -20)(x + -20) = 385 Calculate the square root of the right side: 19.62141687 Break this problem into two subproblems by setting (x + -20) equal to 19.62141687 and -19.62141687.Subproblem 1
x + -20 = 19.62141687 Simplifying x + -20 = 19.62141687 Reorder the terms: -20 + x = 19.62141687 Solving -20 + x = 19.62141687 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '20' to each side of the equation. -20 + 20 + x = 19.62141687 + 20 Combine like terms: -20 + 20 = 0 0 + x = 19.62141687 + 20 x = 19.62141687 + 20 Combine like terms: 19.62141687 + 20 = 39.62141687 x = 39.62141687 Simplifying x = 39.62141687Subproblem 2
x + -20 = -19.62141687 Simplifying x + -20 = -19.62141687 Reorder the terms: -20 + x = -19.62141687 Solving -20 + x = -19.62141687 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '20' to each side of the equation. -20 + 20 + x = -19.62141687 + 20 Combine like terms: -20 + 20 = 0 0 + x = -19.62141687 + 20 x = -19.62141687 + 20 Combine like terms: -19.62141687 + 20 = 0.37858313 x = 0.37858313 Simplifying x = 0.37858313Solution
