To multiply the polynomials (2r-5)(r+4), we can use the distributive property:
(2r - 5)(r + 4) = 2r * r + 2r * 4 - 5 * r - 5 * 4
Simplifying each term, we get:
= 2r^2 + 8r - 5r - 20
Combining like terms:
= 2r^2 + 3r - 20
Therefore, the product of the polynomials (2r-5)(r+4) is 2r^2 + 3r - 20.
(2r - 5)(r + 4) = 2r * r + 2r * 4 - 5 * r - 5 * 4
Simplifying each term, we get:
= 2r^2 + 8r - 5r - 20
Combining like terms:
= 2r^2 + 3r - 20
Therefore, the product of the polynomials (2r-5)(r+4) is 2r^2 + 3r - 20.
