Simplifying x2 + 4x = 56 Reorder the terms: 4x + x2 = 56 Solving 4x + x2 = 56 Solving for variable 'x'. Reorder the terms: -56 + 4x + x2 = 56 + -56 Combine like terms: 56 + -56 = 0 -56 + 4x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '56' to each side of the equation. -56 + 4x + 56 + x2 = 0 + 56 Reorder the terms: -56 + 56 + 4x + x2 = 0 + 56 Combine like terms: -56 + 56 = 0 0 + 4x + x2 = 0 + 56 4x + x2 = 0 + 56 Combine like terms: 0 + 56 = 56 4x + x2 = 56 The x term is 4x. Take half its coefficient (2). Square it (4) and add it to both sides. Add '4' to each side of the equation. 4x + 4 + x2 = 56 + 4 Reorder the terms: 4 + 4x + x2 = 56 + 4 Combine like terms: 56 + 4 = 60 4 + 4x + x2 = 60 Factor a perfect square on the left side: (x + 2)(x + 2) = 60 Calculate the square root of the right side: 7.745966692 Break this problem into two subproblems by setting (x + 2) equal to 7.745966692 and -7.745966692.Subproblem 1
x + 2 = 7.745966692 Simplifying x + 2 = 7.745966692 Reorder the terms: 2 + x = 7.745966692 Solving 2 + x = 7.745966692 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = 7.745966692 + -2 Combine like terms: 2 + -2 = 0 0 + x = 7.745966692 + -2 x = 7.745966692 + -2 Combine like terms: 7.745966692 + -2 = 5.745966692 x = 5.745966692 Simplifying x = 5.745966692Subproblem 2
