Question

Aplique a regra do quadrado da soma de 2 termos: a) (a+c)² b) (×+9)² c) (y+2)² d) (b+5y)² e) (6a+1)² f) (2p+½)² g) (3ab+0,5c)² h) (׳y²+5×)² Me ajudem pfv ❤ Precisa esclarecimento

Answer 1

a) (a+c)² = a^2 + 2ac + c^2

b) (×+9)² = x^2 + 18x + 81

c) (y+2)² = y^2 + 4y + 4

d) (b+5y)² = b^2 + 10by + 25y^2

e) (6a+1)² = 36a^2 + 12a + 1

f) (2p+½)² = 4p^2 + 2p + 1/4

g) (3ab+0,5c)² = 9a^b^2 + 3 abc + 0,25c^2

h) (׳y²+5×)² = x^6y^4 + 10x^4y^2 + 25x^2
