Question

$a) \\ \\ x^{2} + 2xy + y ^{2} \\ \\ \\ b)4a ^{2} - 4ab + b^{2} \\ \\ \\ \\ \\c)25 + 10k + k{2}$
ALGUEME AJUDAAAAAA

Answer 1

(A)

x²+ 2xy + y² = (x+y)²

(B)

4a² - 4ab + b² = (2a-b)²

(C)

25 + 10k + k² = k² + 10k + 25 = (k+5)²

Answer 2

x² + 2xy + y² = (x + y)²

4a² - 4ab + b² = (2a - b)²

k² + 10k + 25 = (k + 5)²
