Question

(4v-1)(5v-3)
multiply and simplify

Answer 1

distribute. use FOIL method.

Answer 2

Here you need to multiply what is inside the left parentheses by what is inside the right parentheses. This means:
(4v - 1)(5v) - (4v - 1)3
5v(4v) -1(5v) - 3(4v) - 3(-1)
20v^2 - 5v -12v +3
20v^2 -17v + 3

This type of multiplication, of a binomial times a binomial is used using FOIL. A binomial is a two term polynomial. Both 4v - 1 and 5v - 3 are binomials. To multoply them together, use FOIL.
Foil stands for
(F)irst
(O)utside
(I)nside
(L)ast
