Simplifying (2x2) + -5x + -4 = 0 Reorder the terms: -4 + -5x + (2x2) = 0 Solving -4 + -5x + (2x2) = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -2 + -2.5x + x2 = 0 Move the constant term to the right: Add '2' to each side of the equation. -2 + -2.5x + 2 + x2 = 0 + 2 Reorder the terms: -2 + 2 + -2.5x + x2 = 0 + 2 Combine like terms: -2 + 2 = 0 0 + -2.5x + x2 = 0 + 2 -2.5x + x2 = 0 + 2 Combine like terms: 0 + 2 = 2 -2.5x + x2 = 2 The x term is -2.5x. Take half its coefficient (-1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. -2.5x + 1.5625 + x2 = 2 + 1.5625 Reorder the terms: 1.5625 + -2.5x + x2 = 2 + 1.5625 Combine like terms: 2 + 1.5625 = 3.5625 1.5625 + -2.5x + x2 = 3.5625 Factor a perfect square on the left side: ((x) + -1.25)((x) + -1.25) = 3.5625 Calculate the square root of the right side: 1.887458609 Break this problem into two subproblems by setting ((x) + -1.25) equal to 1.887458609 and -1.887458609.Subproblem 1
