you familiar with the FOIL method ?

dayakar · Answer

(5r + 2)(3r − 4)
=5r(3r-4)+2(3r-4)

anonymous · Answer

no im not @texaschic101

dayakar · Answer

$$=15r^{2}-20r+6r-8$$

dayakar · Answer

simplify it

texaschic101 · Answer

FOIL.....first, outside, inside, last

(5r + 2)(3r - 4)

First -- multiply first terms in each set....5r * 3r = 15r^2
Outside -- multiply outside terms in each set...5r * -4 = -20r
Inside -- multiply inside terms in each set...2 * 3r = 6r
Last -- multiply last terms in each set...2 * -4 = -8
now put it all together...
15r^2 - 20r + 6r - 8 --- simplify by combining like terms
15r^2 - 14r - 8 <-- your answer
