Simplifying -4x2 + -28x + 3 = 0 Reorder the terms: 3 + -28x + -4x2 = 0 Solving 3 + -28x + -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'. -0.75 + 7x + x2 = 0 Move the constant term to the right: Add '0.75' to each side of the equation. -0.75 + 7x + 0.75 + x2 = 0 + 0.75 Reorder the terms: -0.75 + 0.75 + 7x + x2 = 0 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + 7x + x2 = 0 + 0.75 7x + x2 = 0 + 0.75 Combine like terms: 0 + 0.75 = 0.75 7x + x2 = 0.75 The x term is 7x. Take half its coefficient (3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. 7x + 12.25 + x2 = 0.75 + 12.25 Reorder the terms: 12.25 + 7x + x2 = 0.75 + 12.25 Combine like terms: 0.75 + 12.25 = 13 12.25 + 7x + x2 = 13 Factor a perfect square on the left side: (x + 3.5)(x + 3.5) = 13 Calculate the square root of the right side: 3.605551275 Break this problem into two subproblems by setting (x + 3.5) equal to 3.605551275 and -3.605551275.Subproblem 1
x + 3.5 = 3.605551275 Simplifying x + 3.5 = 3.605551275 Reorder the terms: 3.5 + x = 3.605551275 Solving 3.5 + x = 3.605551275 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + x = 3.605551275 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = 3.605551275 + -3.5 x = 3.605551275 + -3.5 Combine like terms: 3.605551275 + -3.5 = 0.105551275 x = 0.105551275 Simplifying x = 0.105551275Subproblem 2
x + 3.5 = -3.605551275 Simplifying x + 3.5 = -3.605551275 Reorder the terms: 3.5 + x = -3.605551275 Solving 3.5 + x = -3.605551275 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + x = -3.605551275 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = -3.605551275 + -3.5 x = -3.605551275 + -3.5 Combine like terms: -3.605551275 + -3.5 = -7.105551275 x = -7.105551275 Simplifying x = -7.105551275Solution
