Answer 2

Answer:

-12 is the answer to ur Question

Step-by-step explanation:

(3a-2b+c)^2 =>expand it using (a-b+c)^2

(a-b+c)^2=a^2+b^2+c^2-2ab-2bc+2ca

ATQ our expansion will be:

(3a)^2+(2b)^2+(c)^2-(2×3a×2b)-(2×2b×c)+(2×3a×c)

now evalute :

9a^2+4b^2+c^2-12ab-4bc+6ac

Now it's given to find the co-efficient of ab

And here we have -12ab

so the ans will be -12
