where x represents an unknown value, and a, b, and c represent known numbers, where a ≠ 0. (If a = 0 and b ≠ 0 then the equation is linear, not quadratic.)The numbers a, b, and c are the coefficients of the equation and may be distinguished by respectively calling them, the quadratic coefficient, the linear coefficient and the constant coefficient or free term.The most important distinction is that in tasks based on the quadratic functions task shell, the student is presented with a specific quadratic function (either a pure function or a function that models a real-life situation), while in tasks based on the quadratic regression task shell, the student is presented with a set of data and is asked …B.

y = 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.The two solutions are the x-intercepts of the equation, i.e. where the curve crosses the x-axis.
