Multiply the polynomials (2r−5)(r+4) .(2 points) r2+ r+

To multiply the polynomials (2r-5) and (r+4), we can use the distributive property.

First, we multiply 2r by both terms in the second polynomial:

2r * r = 2r^2
2r * 4 = 8r

Next, we multiply -5 by both terms in the second polynomial:

-5 * r = -5r
-5 * 4 = -20

Putting it all together, we get:

(2r-5)(r+4) = 2r^2 + 8r - 5r - 20

Combining like terms:

= 2r^2 + 3r - 20

So the product of the polynomials (2r-5)(r+4) is 2r^2 + 3r - 20.
