Simplifying 6y + 3 = -4y2 Reorder the terms: 3 + 6y = -4y2 Solving 3 + 6y = -4y2 Solving for variable 'y'. Combine like terms: -4y2 + 4y2 = 0 3 + 6y + 4y2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 0.75 + 1.5y + y2 = 0 Move the constant term to the right: Add '-0.75' to each side of the equation. 0.75 + 1.5y + -0.75 + y2 = 0 + -0.75 Reorder the terms: 0.75 + -0.75 + 1.5y + y2 = 0 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + 1.5y + y2 = 0 + -0.75 1.5y + y2 = 0 + -0.75 Combine like terms: 0 + -0.75 = -0.75 1.5y + y2 = -0.75 The y term is 1.5y. Take half its coefficient (0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. 1.5y + 0.5625 + y2 = -0.75 + 0.5625 Reorder the terms: 0.5625 + 1.5y + y2 = -0.75 + 0.5625 Combine like terms: -0.75 + 0.5625 = -0.1875 0.5625 + 1.5y + y2 = -0.1875 Factor a perfect square on the left side: (y + 0.75)(y + 0.75) = -0.1875 Can't calculate square root of the right side. The solution to this equation could not be determined.
