## What Are Quadratic Functions?

Quadratic expressions consists of a coefficient of x^{2}. It is in the form of ax^{2} + bx + c = 0 where a is a non-zero number, b and c can be any real number.

Plotting a quadratic equation:

- Finding the points at which the curve crosses the axes.

Sketching curve:

- Find roots to know where the curve crosses the x-axis.
- Find the point at which curve crosses y-axis by substituting x=0.
- Connect the 3 points to sketch the curve.

Factorising quadratic expressions (ax^{2}+bx+c):

- Think of two numbers that when multiplied gives a×c and when added gives b.
- Check the answer using grid method or by multiplying term by term.
