(3x+2y)^2

6x+4y

it would be better if you posted your answer and we could tell you that you are correct
OpenStudy (anonymous):
ok hold on ima write it out
OpenStudy (anonymous):
or (3x+2y)^2

(3x+2y)(3x+2y)=6x^2+4y^2
OpenStudy (anonymous):
Nope
OpenStudy (anonymous):
9x^2+12xy+4y^2
OpenStudy (anonymous):
u mutiply it ??
OpenStudy (anonymous):
Yeap

FOIL 3x(3x)+3x(2y)+2y(3x)+2y(2y) and simplify and combine like terms
OpenStudy (anonymous):
Or use 3x(3x+2y)+2y(3x+2y)
OpenStudy (anonymous):
Now multiply each and every terms
OpenStudy (anonymous):
o ok so basicaly i mutipliy evrything by the second power :)
OpenStudy (anonymous):
so i got 9x^2+4y^2

no, you are multiplying each term
3x(3x)+3x(2y)+2y(3x)+2y(2y)
9x^2 +6xy +6xy +4Y^2
9x^2+12xy +4y^2
OpenStudy (anonymous):
use this formula
(a+b)^2 = a^2+2ab+b^2
OpenStudy (anonymous):
huh im confused i thought u had to used the 2nd power for each part of the equtaion
OpenStudy (anonymous):
3^2 means 3 * 3
so ( 3x+2y ) ^2 means ( 3x+2y ) ( 3x+2y )
