I know about common factors, difference of squares but what other methods are there. My teacher said 5. Can you aslo give me examples.

The following are methods of solving polynomials. I don't know if these are the exact five your teacher was looking for, but they are ways to solve them...
factorizing --> x² + x - 6 = (x + 3)(x - 2)
difference of squares --> x² - 9 = (x - 3)(x + 3)
completing the squares --> x² + 4x - 3 --> x² + 4x + 4 = 3 + 4 --> (x + 2)² = 7
quadratic formula --> ax² + bx + c --> x = [ -b +/- sqrt(b² - 4ac) ] / 2a
graphing --> draw the graph, find the points where it crosses the x-axis.

well if a polynomial is on the bottom of a fraction you can use the partial fractions method and split it into 2 fractions which is useful in integral calculus

Quadratic equation.

tricky factor. research over the search engines. just that can assist!

there is also difference of cubes,
there is binomial to any power (which would actually give you infinite number of methods....)
