Answer 1

Resposta:

Explicação passo-a-passo:

g)(5+3x)²

(5+3x)·(5+3x)

25+15x+15x+9x²

9x²+30x+25

h)(2x+y)²

(2x+y)·(2x+y)

4x²+2xy+2xy+y²

4x²+4xy+y²

i)(r+4s)²

(r+4s)·(r+4s)

r²+4rs+4rs+16s²

r²+8rs+16s²

j)(10x+y)²

(10x+y)·(10x+y)

100x²+10xy+10xy+y²

100x²+20xy+y²

l)(3y+3x)²

(3y+3x)·(3y+3x)

9y²+9xy+9xy+9x²

9x²+18xy+9y²

m)(-5+n)²

(-5+n)·(-5+n)

25-5n-5n+n²

n²-10n+25

n)(-3x+5)²

(-3x+5)·(-3x+5)

9x²-15x-15x+25

9x²-30x+25

o)(a+ab)²

(a+ab)·(a+ab)

a²+a²b+a²b+ab²

a²+2a²b+ab²

p)(2x+xy)²

(2x+xy)·(2x+xy)

4x²+2x²y+2x²y+xy²

4x²+4x²y+xy²

q)(a²+1)²

(a²+1)·(a²+1)

a^4+a²+a²+1

a^4+2a²+1

PS: a^4 significa a elevado a 4

r)(y³+3)²

(y³+3)·(y³+3)

y^6+3y³+3y³+9

y^6+6y³+9

PS:y^6 significa y elevado a 6.
