Simplifying 3.5 = (0.1 + -1x)(0.15 + -1x) Multiply (0.1 + -1x) * (0.15 + -1x) 3.5 = (0.1(0.15 + -1x) + -1x * (0.15 + -1x)) 3.5 = ((0.15 * 0.1 + -1x * 0.1) + -1x * (0.15 + -1x)) 3.5 = ((0.015 + -0.1x) + -1x * (0.15 + -1x)) 3.5 = (0.015 + -0.1x + (0.15 * -1x + -1x * -1x)) 3.5 = (0.015 + -0.1x + (-0.15x + 1x2)) Combine like terms: -0.1x + -0.15x = -0.25x 3.5 = (0.015 + -0.25x + 1x2) Solving 3.5 = 0.015 + -0.25x + 1x2 Solving for variable 'x'. Combine like terms: 3.5 + -0.015 = 3.485 3.485 + 0.25x + -1x2 = 0.015 + -0.25x + 1x2 + -0.015 + 0.25x + -1x2 Reorder the terms: 3.485 + 0.25x + -1x2 = 0.015 + -0.015 + -0.25x + 0.25x + 1x2 + -1x2 Combine like terms: 0.015 + -0.015 = 0.000 3.485 + 0.25x + -1x2 = 0.000 + -0.25x + 0.25x + 1x2 + -1x2 3.485 + 0.25x + -1x2 = -0.25x + 0.25x + 1x2 + -1x2 Combine like terms: -0.25x + 0.25x = 0.00 3.485 + 0.25x + -1x2 = 0.00 + 1x2 + -1x2 3.485 + 0.25x + -1x2 = 1x2 + -1x2 Combine like terms: 1x2 + -1x2 = 0 3.485 + 0.25x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -3.485 + -0.25x + x2 = 0 Move the constant term to the right: Add '3.485' to each side of the equation. -3.485 + -0.25x + 3.485 + x2 = 0 + 3.485 Reorder the terms: -3.485 + 3.485 + -0.25x + x2 = 0 + 3.485 Combine like terms: -3.485 + 3.485 = 0.000 0.000 + -0.25x + x2 = 0 + 3.485 -0.25x + x2 = 0 + 3.485 Combine like terms: 0 + 3.485 = 3.485 -0.25x + x2 = 3.485 The x term is -0.25x. Take half its coefficient (-0.125). Square it (0.015625) and add it to both sides. Add '0.015625' to each side of the equation. -0.25x + 0.015625 + x2 = 3.485 + 0.015625 Reorder the terms: 0.015625 + -0.25x + x2 = 3.485 + 0.015625 Combine like terms: 3.485 + 0.015625 = 3.500625 0.015625 + -0.25x + x2 = 3.500625 Factor a perfect square on the left side: (x + -0.125)(x + -0.125) = 3.500625 Calculate the square root of the right side: 1.870995724 Break this problem into two subproblems by setting (x + -0.125) equal to 1.870995724 and -1.870995724.Subproblem 1
x + -0.125 = 1.870995724 Simplifying x + -0.125 = 1.870995724 Reorder the terms: -0.125 + x = 1.870995724 Solving -0.125 + x = 1.870995724 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.125' to each side of the equation. -0.125 + 0.125 + x = 1.870995724 + 0.125 Combine like terms: -0.125 + 0.125 = 0.000 0.000 + x = 1.870995724 + 0.125 x = 1.870995724 + 0.125 Combine like terms: 1.870995724 + 0.125 = 1.995995724 x = 1.995995724 Simplifying x = 1.995995724Subproblem 2
