Simplifying (3x2 + -5x + 4) + (3x2 + -1) = 0 Reorder the terms: (4 + -5x + 3x2) + (3x2 + -1) = 0 Remove parenthesis around (4 + -5x + 3x2) 4 + -5x + 3x2 + (3x2 + -1) = 0 Reorder the terms: 4 + -5x + 3x2 + (-1 + 3x2) = 0 Remove parenthesis around (-1 + 3x2) 4 + -5x + 3x2 + -1 + 3x2 = 0 Reorder the terms: 4 + -1 + -5x + 3x2 + 3x2 = 0 Combine like terms: 4 + -1 = 3 3 + -5x + 3x2 + 3x2 = 0 Combine like terms: 3x2 + 3x2 = 6x2 3 + -5x + 6x2 = 0 Solving 3 + -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'. 0.5 + -0.8333333333x + x2 = 0 Move the constant term to the right: Add '-0.5' to each side of the equation. 0.5 + -0.8333333333x + -0.5 + x2 = 0 + -0.5 Reorder the terms: 0.5 + -0.5 + -0.8333333333x + x2 = 0 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + -0.8333333333x + x2 = 0 + -0.5 -0.8333333333x + x2 = 0 + -0.5 Combine like terms: 0 + -0.5 = -0.5 -0.8333333333x + x2 = -0.5 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 = -0.5 + 0.1736111111 Reorder the terms: 0.1736111111 + -0.8333333333x + x2 = -0.5 + 0.1736111111 Combine like terms: -0.5 + 0.1736111111 = -0.3263888889 0.1736111111 + -0.8333333333x + x2 = -0.3263888889 Factor a perfect square on the left side: (x + -0.4166666667)(x + -0.4166666667) = -0.3263888889 Can't calculate square root of the right side. The solution to this equation could not be determined.
