Hello!

To solve this we use the FOIL method (First, Outside, Inside,Last) to multiply the parentheses.

First we multiply the first numbers in each parentheses.

(2x+3)(3x-5)
F. 6x²

Next we multiply the outside numbers.

(2x+3)(3x-5)
O. -10x

Now we multiply the inside numbers.

(2x+3)(3x-5)
I. 9x

And finally we multiply the last numbers.

(2x+3)(3x-5)
L.-15

Now we combine the products we got from FOIL.

6x²-10x+9x-15

We combine like terms.

6x²-x-15

I hope this helps!
