What expression is equivalent to the polynomial given. (4x+3)(3x-8)

The equivalent polynomial is 12x^2 -23x - 24.

You can get this by multiplying the two parenthesis by each other. 

 First start by multiplying the two front numbers:
4x * 3x = 12x^2

Then multiply the outermost numbers:
4x * -8 = -32x

Then multiply the innermost numbers:
3x * 3 = 9x

Then multiply the last numbers: 
3* -8 = -24

Now combine all of them to get the above polynomial.
