Answer 3

\[(3x-5)(3x-5)=\left( 3x-5 \right) ^{2}\]perfect square

Answer 4

if u expand it ,u get trinomial,can u do that

Answer 5

r u there

Answer 6

what do you mean?

Answer 7

\[\left( a-b \right)^{2}=a ^{2}-2ab+b^{2}\]

Answer 8

do u understand above identity

Answer 9

\[\left( 3x-5 \right)^{2}=\left( 3x \right) ^{2}-2*3x*5+5^{2}\]

Answer 10

\[=9x^{2}-30x+25\]

Answer 11

ohhh yes i do :)

so when its aperfect trinomal they are the same :)

Answer 12

above expression contains 3 terms
so, it is called a trinomial

Answer 13

is it clear

Answer 14

yes :)

Answer 15

thank for all the help :)
