Simplifying -2x2 + -5x + -4 = 0 Reorder the terms: -4 + -5x + -2x2 = 0 Solving -4 + -5x + -2x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '-1'. -1(4 + 5x + 2x2) = 0 Ignore the factor -1.Subproblem 1
Set the factor '(4 + 5x + 2x2)' equal to zero and attempt to solve: Simplifying 4 + 5x + 2x2 = 0 Solving 4 + 5x + 2x2 = 0 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 = -0.4375 1.5625 + 2.5x + x2 = -0.4375 Factor a perfect square on the left side: (x + 1.25)(x + 1.25) = -0.4375 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
