Use FOIL (first, outer, inner, last) :
(5h-3)(3h+7)

(5h)(3h)+7(5h)-3(3h)-3(7)
15h^2+35h-9h-21

D: 15h^2+26h-21

Hope this helps :)

Answer:

Option D. 15h² + 26h - 21

Step-by-step explanation:

We have to simplify the product by using distributive property.

(5h - 3)(3h +7) = 5h(3h + 7) - 3(3h + 7)

= 15h² + 35h - 9h -21

= 15h² + 26h -21

Which matches the option D.
