Simplifying 22x2 + -55x + 35 = 0 Reorder the terms: 35 + -55x + 22x2 = 0 Solving 35 + -55x + 22x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 22 the coefficient of the squared term: Divide each side by '22'. 1.590909091 + -2.5x + x2 = 0 Move the constant term to the right: Add '-1.590909091' to each side of the equation. 1.590909091 + -2.5x + -1.590909091 + x2 = 0 + -1.590909091 Reorder the terms: 1.590909091 + -1.590909091 + -2.5x + x2 = 0 + -1.590909091 Combine like terms: 1.590909091 + -1.590909091 = 0.000000000 0.000000000 + -2.5x + x2 = 0 + -1.590909091 -2.5x + x2 = 0 + -1.590909091 Combine like terms: 0 + -1.590909091 = -1.590909091 -2.5x + x2 = -1.590909091 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 = -1.590909091 + 1.5625 Reorder the terms: 1.5625 + -2.5x + x2 = -1.590909091 + 1.5625 Combine like terms: -1.590909091 + 1.5625 = -0.028409091 1.5625 + -2.5x + x2 = -0.028409091 Factor a perfect square on the left side: (x + -1.25)(x + -1.25) = -0.028409091 Can't calculate square root of the right side. The solution to this equation could not be determined.
