Simplifying 5x + 2x2 = -4 Solving 5x + 2x2 = -4 Solving for variable 'x'. Reorder the terms: 4 + 5x + 2x2 = -4 + 4 Combine like terms: -4 + 4 = 0 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.
