Simplifying 1 + -5x = 49 + x2 Solving 1 + -5x = 49 + x2 Solving for variable 'x'. Reorder the terms: 1 + -49 + -5x + -1x2 = 49 + x2 + -49 + -1x2 Combine like terms: 1 + -49 = -48 -48 + -5x + -1x2 = 49 + x2 + -49 + -1x2 Reorder the terms: -48 + -5x + -1x2 = 49 + -49 + x2 + -1x2 Combine like terms: 49 + -49 = 0 -48 + -5x + -1x2 = 0 + x2 + -1x2 -48 + -5x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 -48 + -5x + -1x2 = 0 Factor out the Greatest Common Factor (GCF), '-1'. -1(48 + 5x + x2) = 0 Ignore the factor -1.Subproblem 1
Set the factor '(48 + 5x + x2)' equal to zero and attempt to solve: Simplifying 48 + 5x + x2 = 0 Solving 48 + 5x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-48' to each side of the equation. 48 + 5x + -48 + x2 = 0 + -48 Reorder the terms: 48 + -48 + 5x + x2 = 0 + -48 Combine like terms: 48 + -48 = 0 0 + 5x + x2 = 0 + -48 5x + x2 = 0 + -48 Combine like terms: 0 + -48 = -48 5x + x2 = -48 The x term is 5x. Take half its coefficient (2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. 5x + 6.25 + x2 = -48 + 6.25 Reorder the terms: 6.25 + 5x + x2 = -48 + 6.25 Combine like terms: -48 + 6.25 = -41.75 6.25 + 5x + x2 = -41.75 Factor a perfect square on the left side: (x + 2.5)(x + 2.5) = -41.75 Can't calculate square root of the right side.
