Simplifying 2x2 + 2x + 900 = 0 Reorder the terms: 900 + 2x + 2x2 = 0 Solving 900 + 2x + 2x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2'. 2(450 + x + x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(450 + x + x2)' equal to zero and attempt to solve: Simplifying 450 + x + x2 = 0 Solving 450 + x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-450' to each side of the equation. 450 + x + -450 + x2 = 0 + -450 Reorder the terms: 450 + -450 + x + x2 = 0 + -450 Combine like terms: 450 + -450 = 0 0 + x + x2 = 0 + -450 x + x2 = 0 + -450 Combine like terms: 0 + -450 = -450 x + x2 = -450 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. x + 0.25 + x2 = -450 + 0.25 Reorder the terms: 0.25 + x + x2 = -450 + 0.25 Combine like terms: -450 + 0.25 = -449.75 0.25 + x + x2 = -449.75 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = -449.75 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
