Question

Simplify (3n – 2m)2 = ? 

Answer 1

(3n-2m) (3n-2m)

(you multiply the first number (3n) by the first number in the 2nd bracket (3n) and then by the second number in the 2nd bracket (-2m)), and you do the same for -2m

9n2 - 6mn -6nm +4m2

9n2 -12mn + 4m2

Answer 2

Hi!

(3n - 2m)^2 = 9n^2 - 12mn + 4n^2

The correct answer is D. 9n^2 - 12mn + 4n^2

Hope this helps!
