|Example: Factorise 9x2-24x+16.|
Solution: Given that 9x2-24x+16,
= (3x)2 - 24x + 42
= (3x)2 - 2.3x.4 + 42
This is the form of a2 - 2ab + b2.
\Factors of the given trinomials are (3x-4)(3x-4).
Directions: Find the factors of given trinomials. and show your work. Also write at least ten examples of your own.
