As a graph cuts the axis when the y coordinate is zero, then we substitute \(y = 0\) into the quadratic equation and use algebra to solve. We need to factorise the trinomial. When factorised this ...
Simple situational problems. Standard form of a quadratic equation ax 2 + bx + c = 0, (a ≠0). Solutions of quadratic equations (only real roots) by factorization, and by using quadratic formula.
