GEOMETRICAL REPRESENTATION OF QUADRATIC EXPRESSION Consider the quadratic expression, y = ax2 + bx + c, a ≠0 & a,b,c ∈R then : (i) The graph between x,y is always a parabola. If a > 0, then the shape of the parabola is concave upwards & if a < 0 then the shape of the parabola is concave downwards. (ii) The graph of y = ax2
(Let the roots of the equation ax + bx + c can be divided into 6 categories which are as follows : 2α + bx + c = 0 be and β)
