Question

Solve (s-t)(2s-3t) using the FOIL Method. Include steps

Answer 1

FOIL:
First
Outter
Inner
Last
s*(2s)+(s)*(-3t)+(-t)*(2s)+(-t)*(-3t)
(2s2)+(−3st)+(−2st)+(3t2)==(2s2)+(−3st)+(−2st)+(3t2)=

=2s2−5st+3t2=2s2−5st+3t2.

Answer: (s−t)(2s−3t)=2s2−5st+3t2(s−t)(2s−3t)=2s2−5st+3t2.

Answer 2

multiply everything in the first parenthasis by everything in the second parentahsis

(s-t)(2s-3t) = 2s²-3st-2st+3t² then combine like terms

2s²-5st+3t²
