Simplifying 4x2 + 16x + 50 = 0 Reorder the terms: 50 + 16x + 4x2 = 0 Solving 50 + 16x + 4x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2'. 2(25 + 8x + 2x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(25 + 8x + 2x2)' equal to zero and attempt to solve: Simplifying 25 + 8x + 2x2 = 0 Solving 25 + 8x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 12.5 + 4x + x2 = 0 Move the constant term to the right: Add '-12.5' to each side of the equation. 12.5 + 4x + -12.5 + x2 = 0 + -12.5 Reorder the terms: 12.5 + -12.5 + 4x + x2 = 0 + -12.5 Combine like terms: 12.5 + -12.5 = 0.0 0.0 + 4x + x2 = 0 + -12.5 4x + x2 = 0 + -12.5 Combine like terms: 0 + -12.5 = -12.5 4x + x2 = -12.5 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 = -12.5 + 4 Reorder the terms: 4 + 4x + x2 = -12.5 + 4 Combine like terms: -12.5 + 4 = -8.5 4 + 4x + x2 = -8.5 Factor a perfect square on the left side: (x + 2)(x + 2) = -8.5 Can't calculate square root of the right side.
