Simplifying 3x2 + 6x + 45 = 0 Reorder the terms: 45 + 6x + 3x2 = 0 Solving 45 + 6x + 3x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '3'. 3(15 + 2x + x2) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(15 + 2x + x2)' equal to zero and attempt to solve: Simplifying 15 + 2x + x2 = 0 Solving 15 + 2x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-15' to each side of the equation. 15 + 2x + -15 + x2 = 0 + -15 Reorder the terms: 15 + -15 + 2x + x2 = 0 + -15 Combine like terms: 15 + -15 = 0 0 + 2x + x2 = 0 + -15 2x + x2 = 0 + -15 Combine like terms: 0 + -15 = -15 2x + x2 = -15 The x term is 2x. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2x + 1 + x2 = -15 + 1 Reorder the terms: 1 + 2x + x2 = -15 + 1 Combine like terms: -15 + 1 = -14 1 + 2x + x2 = -14 Factor a perfect square on the left side: (x + 1)(x + 1) = -14 Can't calculate square root of the right side.
