16x^2 - 13x - 27

Explanation:

Distribute each 'pair' of brackets using FOIL , or any method you have for multiplying brackets.

{(5x - 9 )(3x + 4 )] + [ (x - 3 )(x - 3 ) ]

=15x^2+20x-27x-36 + x^2-3x-3x+9

'collect like terms' , starting with the highest power terms and decreasing.

= 16x^2 - 13x - 27
