Simplifying 4(x + 1.2)(x + -8) = 20 Reorder the terms: 4(1.2 + x)(x + -8) = 20 Reorder the terms: 4(1.2 + x)(-8 + x) = 20 Multiply (1.2 + x) * (-8 + x) 4(1.2(-8 + x) + x(-8 + x)) = 20 4((-8 * 1.2 + x * 1.2) + x(-8 + x)) = 20 4((-9.6 + 1.2x) + x(-8 + x)) = 20 4(-9.6 + 1.2x + (-8 * x + x * x)) = 20 4(-9.6 + 1.2x + (-8x + x2)) = 20 Combine like terms: 1.2x + -8x = -6.8x 4(-9.6 + -6.8x + x2) = 20 (-9.6 * 4 + -6.8x * 4 + x2 * 4) = 20 (-38.4 + -27.2x + 4x2) = 20 Solving -38.4 + -27.2x + 4x2 = 20 Solving for variable 'x'. Reorder the terms: -38.4 + -20 + -27.2x + 4x2 = 20 + -20 Combine like terms: -38.4 + -20 = -58.4 -58.4 + -27.2x + 4x2 = 20 + -20 Combine like terms: 20 + -20 = 0 -58.4 + -27.2x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -14.6 + -6.8x + x2 = 0 Move the constant term to the right: Add '14.6' to each side of the equation. -14.6 + -6.8x + 14.6 + x2 = 0 + 14.6 Reorder the terms: -14.6 + 14.6 + -6.8x + x2 = 0 + 14.6 Combine like terms: -14.6 + 14.6 = 0.0 0.0 + -6.8x + x2 = 0 + 14.6 -6.8x + x2 = 0 + 14.6 Combine like terms: 0 + 14.6 = 14.6 -6.8x + x2 = 14.6 The x term is -6.8x. Take half its coefficient (-3.4). Square it (11.56) and add it to both sides. Add '11.56' to each side of the equation. -6.8x + 11.56 + x2 = 14.6 + 11.56 Reorder the terms: 11.56 + -6.8x + x2 = 14.6 + 11.56 Combine like terms: 14.6 + 11.56 = 26.16 11.56 + -6.8x + x2 = 26.16 Factor a perfect square on the left side: (x + -3.4)(x + -3.4) = 26.16 Calculate the square root of the right side: 5.114684741 Break this problem into two subproblems by setting (x + -3.4) equal to 5.114684741 and -5.114684741.Subproblem 1
x + -3.4 = 5.114684741 Simplifying x + -3.4 = 5.114684741 Reorder the terms: -3.4 + x = 5.114684741 Solving -3.4 + x = 5.114684741 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3.4' to each side of the equation. -3.4 + 3.4 + x = 5.114684741 + 3.4 Combine like terms: -3.4 + 3.4 = 0.0 0.0 + x = 5.114684741 + 3.4 x = 5.114684741 + 3.4 Combine like terms: 5.114684741 + 3.4 = 8.514684741 x = 8.514684741 Simplifying x = 8.514684741Subproblem 2
x + -3.4 = -5.114684741 Simplifying x + -3.4 = -5.114684741 Reorder the terms: -3.4 + x = -5.114684741 Solving -3.4 + x = -5.114684741 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3.4' to each side of the equation. -3.4 + 3.4 + x = -5.114684741 + 3.4 Combine like terms: -3.4 + 3.4 = 0.0 0.0 + x = -5.114684741 + 3.4 x = -5.114684741 + 3.4 Combine like terms: -5.114684741 + 3.4 = -1.714684741 x = -1.714684741 Simplifying x = -1.714684741Solution
