Simplifying 7x + 14 = x2 + 4 Reorder the terms: 14 + 7x = x2 + 4 Reorder the terms: 14 + 7x = 4 + x2 Solving 14 + 7x = 4 + x2 Solving for variable 'x'. Reorder the terms: 14 + -4 + 7x + -1x2 = 4 + x2 + -4 + -1x2 Combine like terms: 14 + -4 = 10 10 + 7x + -1x2 = 4 + x2 + -4 + -1x2 Reorder the terms: 10 + 7x + -1x2 = 4 + -4 + x2 + -1x2 Combine like terms: 4 + -4 = 0 10 + 7x + -1x2 = 0 + x2 + -1x2 10 + 7x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 10 + 7x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -10 + -7x + x2 = 0 Move the constant term to the right: Add '10' to each side of the equation. -10 + -7x + 10 + x2 = 0 + 10 Reorder the terms: -10 + 10 + -7x + x2 = 0 + 10 Combine like terms: -10 + 10 = 0 0 + -7x + x2 = 0 + 10 -7x + x2 = 0 + 10 Combine like terms: 0 + 10 = 10 -7x + x2 = 10 The x term is -7x. Take half its coefficient (-3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. -7x + 12.25 + x2 = 10 + 12.25 Reorder the terms: 12.25 + -7x + x2 = 10 + 12.25 Combine like terms: 10 + 12.25 = 22.25 12.25 + -7x + x2 = 22.25 Factor a perfect square on the left side: (x + -3.5)(x + -3.5) = 22.25 Calculate the square root of the right side: 4.716990566 Break this problem into two subproblems by setting (x + -3.5) equal to 4.716990566 and -4.716990566.Subproblem 1
x + -3.5 = 4.716990566 Simplifying x + -3.5 = 4.716990566 Reorder the terms: -3.5 + x = 4.716990566 Solving -3.5 + x = 4.716990566 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3.5' to each side of the equation. -3.5 + 3.5 + x = 4.716990566 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + x = 4.716990566 + 3.5 x = 4.716990566 + 3.5 Combine like terms: 4.716990566 + 3.5 = 8.216990566 x = 8.216990566 Simplifying x = 8.216990566Subproblem 2
x + -3.5 = -4.716990566 Simplifying x + -3.5 = -4.716990566 Reorder the terms: -3.5 + x = -4.716990566 Solving -3.5 + x = -4.716990566 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3.5' to each side of the equation. -3.5 + 3.5 + x = -4.716990566 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + x = -4.716990566 + 3.5 x = -4.716990566 + 3.5 Combine like terms: -4.716990566 + 3.5 = -1.216990566 x = -1.216990566 Simplifying x = -1.216990566Solution
The solution to the problem is based on the solutions from the subproblems. x = {8.216990566, -1.216990566}
