Simplifying 2x2 + 8x + -56 = 0 Reorder the terms: -56 + 8x + 2x2 = 0 Solving -56 + 8x + 2x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2'. 2(-28 + 4x + x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-28 + 4x + x2)' equal to zero and attempt to solve: Simplifying -28 + 4x + x2 = 0 Solving -28 + 4x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '28' to each side of the equation. -28 + 4x + 28 + x2 = 0 + 28 Reorder the terms: -28 + 28 + 4x + x2 = 0 + 28 Combine like terms: -28 + 28 = 0 0 + 4x + x2 = 0 + 28 4x + x2 = 0 + 28 Combine like terms: 0 + 28 = 28 4x + x2 = 28 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 = 28 + 4 Reorder the terms: 4 + 4x + x2 = 28 + 4 Combine like terms: 28 + 4 = 32 4 + 4x + x2 = 32 Factor a perfect square on the left side: (x + 2)(x + 2) = 32 Calculate the square root of the right side: 5.656854249 Break this problem into two subproblems by setting (x + 2) equal to 5.656854249 and -5.656854249.Subproblem 1
x + 2 = 5.656854249 Simplifying x + 2 = 5.656854249 Reorder the terms: 2 + x = 5.656854249 Solving 2 + x = 5.656854249 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 = 5.656854249 + -2 Combine like terms: 2 + -2 = 0 0 + x = 5.656854249 + -2 x = 5.656854249 + -2 Combine like terms: 5.656854249 + -2 = 3.656854249 x = 3.656854249 Simplifying x = 3.656854249Subproblem 2
x + 2 = -5.656854249 Simplifying x + 2 = -5.656854249 Reorder the terms: 2 + x = -5.656854249 Solving 2 + x = -5.656854249 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 = -5.656854249 + -2 Combine like terms: 2 + -2 = 0 0 + x = -5.656854249 + -2 x = -5.656854249 + -2 Combine like terms: -5.656854249 + -2 = -7.656854249 x = -7.656854249 Simplifying x = -7.656854249Solution
