Simplifying 7(4x2 + 5x + 6) + -3(4x2 + 7x + 7) = 0 Reorder the terms: 7(6 + 5x + 4x2) + -3(4x2 + 7x + 7) = 0 (6 * 7 + 5x * 7 + 4x2 * 7) + -3(4x2 + 7x + 7) = 0 (42 + 35x + 28x2) + -3(4x2 + 7x + 7) = 0 Reorder the terms: 42 + 35x + 28x2 + -3(7 + 7x + 4x2) = 0 42 + 35x + 28x2 + (7 * -3 + 7x * -3 + 4x2 * -3) = 0 42 + 35x + 28x2 + (-21 + -21x + -12x2) = 0 Reorder the terms: 42 + -21 + 35x + -21x + 28x2 + -12x2 = 0 Combine like terms: 42 + -21 = 21 21 + 35x + -21x + 28x2 + -12x2 = 0 Combine like terms: 35x + -21x = 14x 21 + 14x + 28x2 + -12x2 = 0 Combine like terms: 28x2 + -12x2 = 16x2 21 + 14x + 16x2 = 0 Solving 21 + 14x + 16x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 16 the coefficient of the squared term: Divide each side by '16'. 1.3125 + 0.875x + x2 = 0 Move the constant term to the right: Add '-1.3125' to each side of the equation. 1.3125 + 0.875x + -1.3125 + x2 = 0 + -1.3125 Reorder the terms: 1.3125 + -1.3125 + 0.875x + x2 = 0 + -1.3125 Combine like terms: 1.3125 + -1.3125 = 0.0000 0.0000 + 0.875x + x2 = 0 + -1.3125 0.875x + x2 = 0 + -1.3125 Combine like terms: 0 + -1.3125 = -1.3125 0.875x + x2 = -1.3125 The x term is 0.875x. Take half its coefficient (0.4375). Square it (0.19140625) and add it to both sides. Add '0.19140625' to each side of the equation. 0.875x + 0.19140625 + x2 = -1.3125 + 0.19140625 Reorder the terms: 0.19140625 + 0.875x + x2 = -1.3125 + 0.19140625 Combine like terms: -1.3125 + 0.19140625 = -1.12109375 0.19140625 + 0.875x + x2 = -1.12109375 Factor a perfect square on the left side: (x + 0.4375)(x + 0.4375) = -1.12109375 Can't calculate square root of the right side. The solution to this equation could not be determined.
