Simplifying 0 = x2 + -14x + -9 Reorder the terms: 0 = -9 + -14x + x2 Solving 0 = -9 + -14x + x2 Solving for variable 'x'. Combine like terms: 0 + 9 = 9 9 + 14x + -1x2 = -9 + -14x + x2 + 9 + 14x + -1x2 Reorder the terms: 9 + 14x + -1x2 = -9 + 9 + -14x + 14x + x2 + -1x2 Combine like terms: -9 + 9 = 0 9 + 14x + -1x2 = 0 + -14x + 14x + x2 + -1x2 9 + 14x + -1x2 = -14x + 14x + x2 + -1x2 Combine like terms: -14x + 14x = 0 9 + 14x + -1x2 = 0 + x2 + -1x2 9 + 14x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 9 + 14x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -9 + -14x + x2 = 0 Move the constant term to the right: Add '9' to each side of the equation. -9 + -14x + 9 + x2 = 0 + 9 Reorder the terms: -9 + 9 + -14x + x2 = 0 + 9 Combine like terms: -9 + 9 = 0 0 + -14x + x2 = 0 + 9 -14x + x2 = 0 + 9 Combine like terms: 0 + 9 = 9 -14x + x2 = 9 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 = 9 + 49 Reorder the terms: 49 + -14x + x2 = 9 + 49 Combine like terms: 9 + 49 = 58 49 + -14x + x2 = 58 Factor a perfect square on the left side: (x + -7)(x + -7) = 58 Calculate the square root of the right side: 7.615773106 Break this problem into two subproblems by setting (x + -7) equal to 7.615773106 and -7.615773106.Subproblem 1
x + -7 = 7.615773106 Simplifying x + -7 = 7.615773106 Reorder the terms: -7 + x = 7.615773106 Solving -7 + x = 7.615773106 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right.
