Weby = a (x-h)^2 + k is the vertex form equation. Now expand the square and simplify. You should get y = a (x^2 -2hx + h^2) + k. Multiply by the coefficient of a and get y = ax^2 -2ahx +ah^2 + k. This is standard form of a quadratic equation, with the normal a, b and c in ax^2 + bx + c equaling a, -2ah and ah^2 + k, respectively. 1 comment ( 20 votes) WebThere are two formulas that are used to find the x and y coordinates. These formulas are: h = -b / (2a) k = c - b 2 / (4a) Example: Find the vertex of the equation 8x 2 - 7x + 1. Solution: Step 1: Identify the values. a = 8 b = -7 c = 1 Step 2: Put the values in the formulas. h = -b / (2a) h = - (-7) / 2 (8) h = 7/16 h = 0.44 k = c - b 2 / (4a)
