Question

calcule d) (x+2)² e) (r+2s)² f) (10x+y)² g) (3y+3a)² h) (-5+n)²​

Answer 1

Explicação passo-a-passo:

d) (x+2)²

(x)²+2(x)(2)+(2)²

x²+4x+4

e) (r+2s)²

(r)²+2(r)(2s)+(2s)²

r²+4rs+4s²

f) (10x+y)

(10x)²+2(10)(x)+(x)²

100x²+20x+x²

g) (3y+3a)²

(3y)²+2(3y)(3a)+(3a)²

9y²+18ay+9a²

h) (-5+n)²

(-5)²+2(-5)(n)+(n)²

25-10n+n²

Bom estudo!!!!
