Simplifying 4y2 + 8 = 3y Reorder the terms: 8 + 4y2 = 3y Solving 8 + 4y2 = 3y Solving for variable 'y'. Reorder the terms: 8 + -3y + 4y2 = 3y + -3y Combine like terms: 3y + -3y = 0 8 + -3y + 4y2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 2 + -0.75y + y2 = 0 Move the constant term to the right: Add '-2' to each side of the equation. 2 + -0.75y + -2 + y2 = 0 + -2 Reorder the terms: 2 + -2 + -0.75y + y2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -0.75y + y2 = 0 + -2 -0.75y + y2 = 0 + -2 Combine like terms: 0 + -2 = -2 -0.75y + y2 = -2 The y term is -0.75y. Take half its coefficient (-0.375). Square it (0.140625) and add it to both sides. Add '0.140625' to each side of the equation. -0.75y + 0.140625 + y2 = -2 + 0.140625 Reorder the terms: 0.140625 + -0.75y + y2 = -2 + 0.140625 Combine like terms: -2 + 0.140625 = -1.859375 0.140625 + -0.75y + y2 = -1.859375 Factor a perfect square on the left side: (y + -0.375)(y + -0.375) = -1.859375 Can't calculate square root of the right side. The solution to this equation could not be determined.
