Simplifying 2x2 + 5x + -8 = -13 Reorder the terms: -8 + 5x + 2x2 = -13 Solving -8 + 5x + 2x2 = -13 Solving for variable 'x'. Reorder the terms: -8 + 13 + 5x + 2x2 = -13 + 13 Combine like terms: -8 + 13 = 5 5 + 5x + 2x2 = -13 + 13 Combine like terms: -13 + 13 = 0 5 + 5x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 2.5 + 2.5x + x2 = 0 Move the constant term to the right: Add '-2.5' to each side of the equation. 2.5 + 2.5x + -2.5 + x2 = 0 + -2.5 Reorder the terms: 2.5 + -2.5 + 2.5x + x2 = 0 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + 2.5x + x2 = 0 + -2.5 2.5x + x2 = 0 + -2.5 Combine like terms: 0 + -2.5 = -2.5 2.5x + x2 = -2.5 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 = -2.5 + 1.5625 Reorder the terms: 1.5625 + 2.5x + x2 = -2.5 + 1.5625 Combine like terms: -2.5 + 1.5625 = -0.9375 1.5625 + 2.5x + x2 = -0.9375 Factor a perfect square on the left side: (x + 1.25)(x + 1.25) = -0.9375 Can't calculate square root of the right side. The solution to this equation could not be determined.
