Simplifying 0 = x2 + 14x + -105 Reorder the terms: 0 = -105 + 14x + x2 Solving 0 = -105 + 14x + x2 Solving for variable 'x'. Combine like terms: 0 + 105 = 105 105 + -14x + -1x2 = -105 + 14x + x2 + 105 + -14x + -1x2 Reorder the terms: 105 + -14x + -1x2 = -105 + 105 + 14x + -14x + x2 + -1x2 Combine like terms: -105 + 105 = 0 105 + -14x + -1x2 = 0 + 14x + -14x + x2 + -1x2 105 + -14x + -1x2 = 14x + -14x + x2 + -1x2 Combine like terms: 14x + -14x = 0 105 + -14x + -1x2 = 0 + x2 + -1x2 105 + -14x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 105 + -14x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -105 + 14x + x2 = 0 Move the constant term to the right: Add '105' to each side of the equation. -105 + 14x + 105 + x2 = 0 + 105 Reorder the terms: -105 + 105 + 14x + x2 = 0 + 105 Combine like terms: -105 + 105 = 0 0 + 14x + x2 = 0 + 105 14x + x2 = 0 + 105 Combine like terms: 0 + 105 = 105 14x + x2 = 105 The x term is 14x. Take half its coefficient (7). Square it (49) and add it to both sides. Add '49' to each side of the equation. 14x + 49 + x2 = 105 + 49 Reorder the terms: 49 + 14x + x2 = 105 + 49 Combine like terms: 105 + 49 = 154 49 + 14x + x2 = 154 Factor a perfect square on the left side: (x + 7)(x + 7) = 154 Calculate the square root of the right side: 12.409673646 Break this problem into two subproblems by setting (x + 7) equal to 12.409673646 and -12.409673646.Subproblem 1
x + 7 = 12.409673646 Simplifying x + 7 = 12.409673646 Reorder the terms: 7 + x = 12.409673646 Solving 7 + x = 12.409673646 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + x = 12.409673646 + -7 Combine like terms: 7 + -7 = 0 0 + x = 12.409673646 + -7 x = 12.409673646 + -7 Combine like terms: 12.409673646 + -7 = 5.409673646 x = 5.409673646 Simplifying x = 5.409673646Subproblem 2
x + 7 = -12.409673646 Simplifying x + 7 = -12.409673646 Reorder the terms: 7 + x = -12.409673646 Solving 7 + x = -12.409673646 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right.
