Answer 2

Answer:

The square of (3x - 4y) is (9x^2 + 16y^2 - 24xy).

The steps to solve this question is given below.

(3x - 4y) = (3x - 4y)^2 = (3x)^2 + (4y)^2 - (2×3x×4y) = (9x^2 + 16y^2 - 24xy).

Step-by-step explanation:

By using the algebraic identity, (a - b)^2 = (a^2 + b^2 - 2ab).

So, the solution of this question is (9x^2 + 16y^2 - 24xy).
