Simplifying -6p2 + 7p + -9 = 0 Reorder the terms: -9 + 7p + -6p2 = 0 Solving -9 + 7p + -6p2 = 0 Solving for variable 'p'. Begin completing the square. Divide all terms by -6 the coefficient of the squared term: Divide each side by '-6'. 1.5 + -1.166666667p + p2 = 0 Move the constant term to the right: Add '-1.5' to each side of the equation. 1.5 + -1.166666667p + -1.5 + p2 = 0 + -1.5 Reorder the terms: 1.5 + -1.5 + -1.166666667p + p2 = 0 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + -1.166666667p + p2 = 0 + -1.5 -1.166666667p + p2 = 0 + -1.5 Combine like terms: 0 + -1.5 = -1.5 -1.166666667p + p2 = -1.5 The p term is -1.166666667p. Take half its coefficient (-0.5833333335). Square it (0.3402777780) and add it to both sides. Add '0.3402777780' to each side of the equation. -1.166666667p + 0.3402777780 + p2 = -1.5 + 0.3402777780 Reorder the terms: 0.3402777780 + -1.166666667p + p2 = -1.5 + 0.3402777780 Combine like terms: -1.5 + 0.3402777780 = -1.159722222 0.3402777780 + -1.166666667p + p2 = -1.159722222 Factor a perfect square on the left side: (p + -0.5833333335)(p + -0.5833333335) = -1.159722222 Can't calculate square root of the right side. The solution to this equation could not be determined.
