Which of the following is the square of a binomial?
A)m^2-mn+n^2
B)c^2-2cd+d^2
C)16x^2 + 9y^2
D)a^2+b^2

Respuesta :

Answer: Choice B

c^2-2cd+d^2 = (c-d)^2

We can verify this with the following steps

(c-d)^2 = (c-d)(c-d)

(c-d)^2 = c(c-d) - d(c-d)

(c-d)^2 = c^2-cd-cd+d^2

(c-d)^2 = c^2-2cd+d^2
