Simplifying x2 + 8x + 4 = 12 Reorder the terms: 4 + 8x + x2 = 12 Solving 4 + 8x + x2 = 12 Solving for variable 'x'. Reorder the terms: 4 + -12 + 8x + x2 = 12 + -12 Combine like terms: 4 + -12 = -8 -8 + 8x + x2 = 12 + -12 Combine like terms: 12 + -12 = 0 -8 + 8x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '8' to each side of the equation. -8 + 8x + 8 + x2 = 0 + 8 Reorder the terms: -8 + 8 + 8x + x2 = 0 + 8 Combine like terms: -8 + 8 = 0 0 + 8x + x2 = 0 + 8 8x + x2 = 0 + 8 Combine like terms: 0 + 8 = 8 8x + x2 = 8 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 = 8 + 16 Reorder the terms: 16 + 8x + x2 = 8 + 16 Combine like terms: 8 + 16 = 24 16 + 8x + x2 = 24 Factor a perfect square on the left side: (x + 4)(x + 4) = 24 Calculate the square root of the right side: 4.898979486 Break this problem into two subproblems by setting (x + 4) equal to 4.898979486 and -4.898979486.Subproblem 1
x + 4 = 4.898979486 Simplifying x + 4 = 4.898979486 Reorder the terms: 4 + x = 4.898979486 Solving 4 + x = 4.898979486 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 = 4.898979486 + -4 Combine like terms: 4 + -4 = 0 0 + x = 4.898979486 + -4 x = 4.898979486 + -4 Combine like terms: 4.898979486 + -4 = 0.898979486 x = 0.898979486 Simplifying x = 0.898979486Subproblem 2
x + 4 = -4.898979486 Simplifying x + 4 = -4.898979486 Reorder the terms: 4 + x = -4.898979486 Solving 4 + x = -4.898979486 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 = -4.898979486 + -4 Combine like terms: 4 + -4 = 0 0 + x = -4.898979486 + -4 x = -4.898979486 + -4 Combine like terms: -4.898979486 + -4 = -8.898979486 x = -8.898979486 Simplifying x = -8.898979486Solution
