Simplifying x2 + -6x + 16 = 7 + 2x Reorder the terms: 16 + -6x + x2 = 7 + 2x Solving 16 + -6x + x2 = 7 + 2x Solving for variable 'x'. Reorder the terms: 16 + -7 + -6x + -2x + x2 = 7 + 2x + -7 + -2x Combine like terms: 16 + -7 = 9 9 + -6x + -2x + x2 = 7 + 2x + -7 + -2x Combine like terms: -6x + -2x = -8x 9 + -8x + x2 = 7 + 2x + -7 + -2x Reorder the terms: 9 + -8x + x2 = 7 + -7 + 2x + -2x Combine like terms: 7 + -7 = 0 9 + -8x + x2 = 0 + 2x + -2x 9 + -8x + x2 = 2x + -2x Combine like terms: 2x + -2x = 0 9 + -8x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-9' to each side of the equation. 9 + -8x + -9 + x2 = 0 + -9 Reorder the terms: 9 + -9 + -8x + x2 = 0 + -9 Combine like terms: 9 + -9 = 0 0 + -8x + x2 = 0 + -9 -8x + x2 = 0 + -9 Combine like terms: 0 + -9 = -9 -8x + x2 = -9 The x term is -8x. Take half its coefficient (-4). Square it (16) and add it to both sides. Add '16' to each side of the equation. -8x + 16 + x2 = -9 + 16 Reorder the terms: 16 + -8x + x2 = -9 + 16 Combine like terms: -9 + 16 = 7 16 + -8x + x2 = 7 Factor a perfect square on the left side: (x + -4)(x + -4) = 7 Calculate the square root of the right side: 2.645751311 Break this problem into two subproblems by setting (x + -4) equal to 2.645751311 and -2.645751311.Subproblem 1
x + -4 = 2.645751311 Simplifying x + -4 = 2.645751311 Reorder the terms: -4 + x = 2.645751311 Solving -4 + x = 2.645751311 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + x = 2.645751311 + 4 Combine like terms: -4 + 4 = 0 0 + x = 2.645751311 + 4 x = 2.645751311 + 4 Combine like terms: 2.645751311 + 4 = 6.645751311 x = 6.645751311 Simplifying x = 6.645751311Subproblem 2
x + -4 = -2.645751311 Simplifying x + -4 = -2.645751311 Reorder the terms: -4 + x = -2.645751311 Solving -4 + x = -2.645751311 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right.
