Simplifying 4x2 + -5x + -8 = 12 Reorder the terms: -8 + -5x + 4x2 = 12 Solving -8 + -5x + 4x2 = 12 Solving for variable 'x'. Reorder the terms: -8 + -12 + -5x + 4x2 = 12 + -12 Combine like terms: -8 + -12 = -20 -20 + -5x + 4x2 = 12 + -12 Combine like terms: 12 + -12 = 0 -20 + -5x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -5 + -1.25x + x2 = 0 Move the constant term to the right: Add '5' to each side of the equation. -5 + -1.25x + 5 + x2 = 0 + 5 Reorder the terms: -5 + 5 + -1.25x + x2 = 0 + 5 Combine like terms: -5 + 5 = 0 0 + -1.25x + x2 = 0 + 5 -1.25x + x2 = 0 + 5 Combine like terms: 0 + 5 = 5 -1.25x + x2 = 5 The x term is -1.25x. Take half its coefficient (-0.625). Square it (0.390625) and add it to both sides. Add '0.390625' to each side of the equation. -1.25x + 0.390625 + x2 = 5 + 0.390625 Reorder the terms: 0.390625 + -1.25x + x2 = 5 + 0.390625 Combine like terms: 5 + 0.390625 = 5.390625 0.390625 + -1.25x + x2 = 5.390625 Factor a perfect square on the left side: (x + -0.625)(x + -0.625) = 5.390625 Calculate the square root of the right side: 2.321771953 Break this problem into two subproblems by setting (x + -0.625) equal to 2.321771953 and -2.321771953.Subproblem 1
x + -0.625 = 2.321771953 Simplifying x + -0.625 = 2.321771953 Reorder the terms: -0.625 + x = 2.321771953 Solving -0.625 + x = 2.321771953 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.625' to each side of the equation. -0.625 + 0.625 + x = 2.321771953 + 0.625 Combine like terms: -0.625 + 0.625 = 0.000 0.000 + x = 2.321771953 + 0.625 x = 2.321771953 + 0.625 Combine like terms: 2.321771953 + 0.625 = 2.946771953 x = 2.946771953 Simplifying x = 2.946771953Subproblem 2
x + -0.625 = -2.321771953 Simplifying x + -0.625 = -2.321771953 Reorder the terms: -0.625 + x = -2.321771953 Solving -0.625 + x = -2.321771953 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.625' to each side of the equation. -0.625 + 0.625 + x = -2.321771953 + 0.625 Combine like terms: -0.625 + 0.625 = 0.000 0.000 + x = -2.321771953 + 0.625 x = -2.321771953 + 0.625 Combine like terms: -2.321771953 + 0.625 = -1.696771953 x = -1.696771953 Simplifying x = -1.696771953Solution
