Use FOIL:
(2r − 5)(r + 4)
= 2r·r + 2r·4 − 5·r − 5·4
= 2r^2 + 8r − 5r − 20
= 2r^2 + 3r − 20
So the product is 2r^2 + 3r − 20 (which includes the r^2 and r terms).
(2r − 5)(r + 4)
= 2r·r + 2r·4 − 5·r − 5·4
= 2r^2 + 8r − 5r − 20
= 2r^2 + 3r − 20
So the product is 2r^2 + 3r − 20 (which includes the r^2 and r terms).
