(5a-4)(3a-1) How do I do it?

Mathematics
1 answer:
olga_2 [115]2 years ago
8 0

Answer:

15a^2 -17a +4

5a x 3a = 15a^2 bc a times a makes it squared.

next, 5a x -1 = -5a

and then -4 x 3a = -12a

-5a -12a (bc they're like terms) = -17a

then, -4 x -1= 4 ( two negs cancel each other out)

I apologize for my mistake the first time
