Set the factor '(3 + 4x + 4x2)' equal to zero and attempt to solve: Simplifying 3 + 4x + 4x2 = 0 Solving 3 + 4x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 0.75 + x + x2 = 0 Move the constant term to the right: Add '-0.75' to each side of the equation. 0.75 + x + -0.75 + x2 = 0 + -0.75 Reorder the terms: 0.75 + -0.75 + x + x2 = 0 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + x + x2 = 0 + -0.75 x + x2 = 0 + -0.75 Combine like terms: 0 + -0.75 = -0.75 x + x2 = -0.75 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. + 0.25 + x2 = -0.75 + 0.25 Combine like terms: + 0.25 = 1.25 1.25 + x2 = -0.75 + 0.25 Combine like terms: -0.75 + 0.25 = -0.5 1.25 + x2 = -0.5 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = -0.5 Can't calculate square root of the right side.
