Simplifying x(8x + 77) = 3x2 + -7x + 3 Reorder the terms: x(77 + 8x) = 3x2 + -7x + 3 (77 * x + 8x * x) = 3x2 + -7x + 3 (77x + 8x2) = 3x2 + -7x + 3 Reorder the terms: 77x + 8x2 = 3 + -7x + 3x2 Solving 77x + 8x2 = 3 + -7x + 3x2 Solving for variable 'x'. Reorder the terms: -3 + 77x + 7x + 8x2 + -3x2 = 3 + -7x + 3x2 + -3 + 7x + -3x2 Combine like terms: 77x + 7x = 84x -3 + 84x + 8x2 + -3x2 = 3 + -7x + 3x2 + -3 + 7x + -3x2 Combine like terms: 8x2 + -3x2 = 5x2 -3 + 84x + 5x2 = 3 + -7x + 3x2 + -3 + 7x + -3x2 Reorder the terms: -3 + 84x + 5x2 = 3 + -3 + -7x + 7x + 3x2 + -3x2 Combine like terms: 3 + -3 = 0 -3 + 84x + 5x2 = 0 + -7x + 7x + 3x2 + -3x2 -3 + 84x + 5x2 = -7x + 7x + 3x2 + -3x2 Combine like terms: -7x + 7x = 0 -3 + 84x + 5x2 = 0 + 3x2 + -3x2 -3 + 84x + 5x2 = 3x2 + -3x2 Combine like terms: 3x2 + -3x2 = 0 -3 + 84x + 5x2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -0.6 + 16.8x + x2 = 0 Move the constant term to the right: Add '0.6' to each side of the equation. -0.6 + 16.8x + 0.6 + x2 = 0 + 0.6 Reorder the terms: -0.6 + 0.6 + 16.8x + x2 = 0 + 0.6 Combine like terms: -0.6 + 0.6 = 0.0 0.0 + 16.8x + x2 = 0 + 0.6 16.8x + x2 = 0 + 0.6 Combine like terms: 0 + 0.6 = 0.6 16.8x + x2 = 0.6 The x term is 16.8x. Take half its coefficient (8.4). Square it (70.56) and add it to both sides. Add '70.56' to each side of the equation. 16.8x + 70.56 + x2 = 0.6 + 70.56 Reorder the terms: 70.56 + 16.8x + x2 = 0.6 + 70.56 Combine like terms: 0.6 + 70.56 = 71.16 70.56 + 16.8x + x2 = 71.16 Factor a perfect square on the left side: (x + 8.4)(x + 8.4) = 71.16 Calculate the square root of the right side: 8.435638684 Break this problem into two subproblems by setting (x + 8.4) equal to 8.435638684 and -8.435638684.Subproblem 1
x + 8.4 = 8.435638684 Simplifying x + 8.4 = 8.435638684 Reorder the terms: 8.4 + x = 8.435638684 Solving 8.4 + x = 8.435638684 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-8.4' to each side of the equation. 8.4 + -8.4 + x = 8.435638684 + -8.4 Combine like terms: 8.4 + -8.4 = 0.0 0.0 + x = 8.435638684 + -8.4 x = 8.435638684 + -8.4 Combine like terms: 8.435638684 + -8.4 = 0.035638684 x = 0.035638684 Simplifying x = 0.035638684Subproblem 2
x + 8.4 = -8.435638684 Simplifying x + 8.4 = -8.435638684 Reorder the terms: 8.4 + x = -8.435638684 Solving 8.4 + x = -8.435638684 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-8.4' to each side of the equation. 8.4 + -8.4 + x = -8.435638684 + -8.4 Combine like terms: 8.4 + -8.4 = 0.0 0.0 + x = -8.435638684 + -8.4 x = -8.435638684 + -8.4 Combine like terms: -8.435638684 + -8.4 = -16.835638684 x = -16.835638684 Simplifying x = -16.835638684Solution
