Question

Expand: (2x-5y)^2
answer it step by step​

Answer 1

Answer:

$(2x - 5y) {}^{2} \\ = (2x) {}^{2} - 2.2x.5y + (5y) {}^{2} \\ = 4x {}^{2} - 20xy + 25y {}^{2}$

Step-by-step explanation:

Hope my answer will help you

Answer 2

(2x-5y)^2

= (2x)^2 + (5y)^2 - 2(2x*5y)

= 4x^2 + 25y^2 - 2(10xy)

Therefore, the answer is : 4x^2 + 25y^2 - 20xy
