Simplifying (7x2 + -1x + 2) + -1(x2 + 4x + -4) = 0 Reorder the terms: (2 + -1x + 7x2) + -1(x2 + 4x + -4) = 0 Remove parenthesis around (2 + -1x + 7x2) 2 + -1x + 7x2 + -1(x2 + 4x + -4) = 0 Reorder the terms: 2 + -1x + 7x2 + -1(-4 + 4x + x2) = 0 2 + -1x + 7x2 + (-4 * -1 + 4x * -1 + x2 * -1) = 0 2 + -1x + 7x2 + (4 + -4x + -1x2) = 0 Reorder the terms: 2 + 4 + -1x + -4x + 7x2 + -1x2 = 0 Combine like terms: 2 + 4 = 6 6 + -1x + -4x + 7x2 + -1x2 = 0 Combine like terms: -1x + -4x = -5x 6 + -5x + 7x2 + -1x2 = 0 Combine like terms: 7x2 + -1x2 = 6x2 6 + -5x + 6x2 = 0 Solving 6 + -5x + 6x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 6 the coefficient of the squared term: Divide each side by '6'. 1 + -0.8333333333x + x2 = 0 Move the constant term to the right: Add '-1' to each side of the equation. 1 + -0.8333333333x + -1 + x2 = 0 + -1 Reorder the terms: 1 + -1 + -0.8333333333x + x2 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -0.8333333333x + x2 = 0 + -1 -0.8333333333x + x2 = 0 + -1 Combine like terms: 0 + -1 = -1 -0.8333333333x + x2 = -1 The x term is -0.8333333333x. Take half its coefficient (-0.4166666667). Square it (0.1736111111) and add it to both sides. Add '0.1736111111' to each side of the equation. -0.8333333333x + 0.1736111111 + x2 = -1 + 0.1736111111 Reorder the terms: 0.1736111111 + -0.8333333333x + x2 = -1 + 0.1736111111 Combine like terms: -1 + 0.1736111111 = -0.8263888889 0.1736111111 + -0.8333333333x + x2 = -0.8263888889 Factor a perfect square on the left side: (x + -0.4166666667)(x + -0.4166666667) = -0.8263888889 Can't calculate square root of the right side. The solution to this equation could not be determined.
