Simplifying 5x2 + -12x + -78 = 0 Reorder the terms: -78 + -12x + 5x2 = 0 Solving -78 + -12x + 5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -15.6 + -2.4x + x2 = 0 Move the constant term to the right: Add '15.6' to each side of the equation. -15.6 + -2.4x + 15.6 + x2 = 0 + 15.6 Reorder the terms: -15.6 + 15.6 + -2.4x + x2 = 0 + 15.6 Combine like terms: -15.6 + 15.6 = 0.0 0.0 + -2.4x + x2 = 0 + 15.6 -2.4x + x2 = 0 + 15.6 Combine like terms: 0 + 15.6 = 15.6 -2.4x + x2 = 15.6 The x term is -2.4x. Take half its coefficient (-1.2). Square it (1.44) and add it to both sides. Add '1.44' to each side of the equation. -2.4x + 1.44 + x2 = 15.6 + 1.44 Reorder the terms: 1.44 + -2.4x + x2 = 15.6 + 1.44 Combine like terms: 15.6 + 1.44 = 17.04 1.44 + -2.4x + x2 = 17.04 Factor a perfect square on the left side: (x + -1.2)(x + -1.2) = 17.04 Calculate the square root of the right side: 4.127953488 Break this problem into two subproblems by setting (x + -1.2) equal to 4.127953488 and -4.127953488.Subproblem 1
x + -1.2 = 4.127953488 Simplifying x + -1.2 = 4.127953488 Reorder the terms: -1.2 + x = 4.127953488 Solving -1.2 + x = 4.127953488 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.2' to each side of the equation. -1.2 + 1.2 + x = 4.127953488 + 1.2 Combine like terms: -1.2 + 1.2 = 0.0 0.0 + x = 4.127953488 + 1.2 x = 4.127953488 + 1.2 Combine like terms: 4.127953488 + 1.2 = 5.327953488 x = 5.327953488 Simplifying x = 5.327953488Subproblem 2
x + -1.2 = -4.127953488 Simplifying x + -1.2 = -4.127953488 Reorder the terms: -1.2 + x = -4.127953488 Solving -1.2 + x = -4.127953488 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.2' to each side of the equation. -1.2 + 1.2 + x = -4.127953488 + 1.2 Combine like terms: -1.2 + 1.2 = 0.0 0.0 + x = -4.127953488 + 1.2 x = -4.127953488 + 1.2 Combine like terms: -4.127953488 + 1.2 = -2.927953488 x = -2.927953488 Simplifying x = -2.927953488Solution
