Simplifying 2x2 + 7 = 5x + -11 Reorder the terms: 7 + 2x2 = 5x + -11 Reorder the terms: 7 + 2x2 = -11 + 5x Solving 7 + 2x2 = -11 + 5x Solving for variable 'x'. Reorder the terms: 7 + 11 + -5x + 2x2 = -11 + 5x + 11 + -5x Combine like terms: 7 + 11 = 18 18 + -5x + 2x2 = -11 + 5x + 11 + -5x Reorder the terms: 18 + -5x + 2x2 = -11 + 11 + 5x + -5x Combine like terms: -11 + 11 = 0 18 + -5x + 2x2 = 0 + 5x + -5x 18 + -5x + 2x2 = 5x + -5x Combine like terms: 5x + -5x = 0 18 + -5x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 9 + -2.5x + x2 = 0 Move the constant term to the right: Add '-9' to each side of the equation. 9 + -2.5x + -9 + x2 = 0 + -9 Reorder the terms: 9 + -9 + -2.5x + x2 = 0 + -9 Combine like terms: 9 + -9 = 0 0 + -2.5x + x2 = 0 + -9 -2.5x + x2 = 0 + -9 Combine like terms: 0 + -9 = -9 -2.5x + x2 = -9 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 = -9 + 1.5625 Reorder the terms: 1.5625 + -2.5x + x2 = -9 + 1.5625 Combine like terms: -9 + 1.5625 = -7.4375 1.5625 + -2.5x + x2 = -7.4375 Factor a perfect square on the left side: (x + -1.25)(x + -1.25) = -7.4375 Can't calculate square root of the right side. The solution to this equation could not be determined.
