Simplifying 4x2 + -20x + -19 = 0 Reorder the terms: -19 + -20x + 4x2 = 0 Solving -19 + -20x + 4x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -4.75 + -5x + x2 = 0 Move the constant term to the right: Add '4.75' to each side of the equation. -4.75 + -5x + 4.75 + x2 = 0 + 4.75 Reorder the terms: -4.75 + 4.75 + -5x + x2 = 0 + 4.75 Combine like terms: -4.75 + 4.75 = 0.00 0.00 + -5x + x2 = 0 + 4.75 -5x + x2 = 0 + 4.75 Combine like terms: 0 + 4.75 = 4.75 -5x + x2 = 4.75 The x term is -5x. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5x + 6.25 + x2 = 4.75 + 6.25 Reorder the terms: 6.25 + -5x + x2 = 4.75 + 6.25 Combine like terms: 4.75 + 6.25 = 11 6.25 + -5x + x2 = 11 Factor a perfect square on the left side: (x + -2.5)(x + -2.5) = 11 Calculate the square root of the right side: 3.31662479 Break this problem into two subproblems by setting (x + -2.5) equal to 3.31662479 and -3.31662479.Subproblem 1
x + -2.5 = 3.31662479 Simplifying x + -2.5 = 3.31662479 Reorder the terms: -2.5 + x = 3.31662479 Solving -2.5 + x = 3.31662479 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + x = 3.31662479 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = 3.31662479 + 2.5 x = 3.31662479 + 2.5 Combine like terms: 3.31662479 + 2.5 = 5.81662479 x = 5.81662479 Simplifying x = 5.81662479Subproblem 2
x + -2.5 = -3.31662479 Simplifying x + -2.5 = -3.31662479 Reorder the terms: -2.5 + x = -3.31662479 Solving -2.5 + x = -3.31662479 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + x = -3.31662479 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = -3.31662479 + 2.5 x = -3.31662479 + 2.5 Combine like terms: -3.31662479 + 2.5 = -0.81662479 x = -0.81662479 Simplifying x = -0.81662479Solution
