Question 129760
 Use FOIL to multiply:
(4x – 9)(3x – 5) 

FOIL is an acronym used to help the student remember how to multiply expressions of the form (a+b)(c+d).  It stands for:

F=First 
O=Outer
I=Inner 
L=Last


If we apply this to your problem, we get:

First--------------4x*3x=12x^2
Outer---------------4x*(-5)=-20x
Inner---------------(-9)*3x=-27x
Last-------------------(-9)(-5)=45

Now if we add the terms up, we get:

12x^2-47x+45
