If the second polynomial is x + 2y -3, we multiply
    (4x - 3y + 5) (x + 2y - 3)

We distribute each term of the first polynomial (4x - 3y + 5) to every term

of the second polynomial (x + 2y - 3):   
    (4x - 3y + 5) (x + 2y - 3) = 4x^​2 + 8xy - 12x
                                                       - 3xy          - 6y^​2 +   9y
                                                                +  5x            + 10y - 15

Then combine similar terms:
    (4x - 3y + 5) (x + 2y - 3) = 4x^​2 - 6y^​2 + 5xy - 7x + 19y - 15


If the second polynomial is x + 2y --3, we multiply
    (4x - 3y + 5) (x + 2y + 3) = 4x^​2 + 8xy + 12x
                                                        - 3xy          - 6y^​2 -   9y
                                                                  +  5x          + 10y + 15

    (4x - 3y + 5) (x + 2y - 3) = 4x^​2 - 6y^​2 + 5xy + 17x + y + 15

Answer:

see my explanation!!

Step-by-step explanation:

I think you accidentally typed in 2 minuse right?

so the answer i got i s4x^2-6y+5xy-7x+19y-15
