2x^2+3x-54

Step-by-step explanation:

The given expression is (2x-9)(x+6)

Distributive property:

a(b+c)=ab+ac

or (b+c)a=ba+ca

By distributive property the above expression will be written as :

$(2x-9)x+(2x-9)6\\\\(2x)x-9x+(2x)(6)-(9)(6)\\\\2x^2-9x+12x-54\\\\2x^2+(-9+12)x-54\\\\2x^2+3x-54$

Hence, (2x-9)(x+6)=2x^2+3x-54
