Simplifying 4p2 + -3p + 9 = 2 Reorder the terms: 9 + -3p + 4p2 = 2 Solving 9 + -3p + 4p2 = 2 Solving for variable 'p'. Reorder the terms: 9 + -2 + -3p + 4p2 = 2 + -2 Combine like terms: 9 + -2 = 7 7 + -3p + 4p2 = 2 + -2 Combine like terms: 2 + -2 = 0 7 + -3p + 4p2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 1.75 + -0.75p + p2 = 0 Move the constant term to the right: Add '-1.75' to each side of the equation. 1.75 + -0.75p + -1.75 + p2 = 0 + -1.75 Reorder the terms: 1.75 + -1.75 + -0.75p + p2 = 0 + -1.75 Combine like terms: 1.75 + -1.75 = 0.00 0.00 + -0.75p + p2 = 0 + -1.75 -0.75p + p2 = 0 + -1.75 Combine like terms: 0 + -1.75 = -1.75 -0.75p + p2 = -1.75 The p term is -0.75p. 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. -0.75p + 0.140625 + p2 = -1.75 + 0.140625 Reorder the terms: 0.140625 + -0.75p + p2 = -1.75 + 0.140625 Combine like terms: -1.75 + 0.140625 = -1.609375 0.140625 + -0.75p + p2 = -1.609375 Factor a perfect square on the left side: (p + -0.375)(p + -0.375) = -1.609375 Can't calculate square root of the right side. The solution to this equation could not be determined.
