Answer 1

Resposta:

A) (x+y)² =

x²+2.x.y+y² =

x²+2xy+y²

B) (a+7)² =

a²+2.a.7+7² =

a²+14a+49

C) (3x+1)² =

(3x)²+2.3x.1+1² =

9x²+6x+1

D) (10y+x)² =

(10y)²+2.10y.x+x²

100y²+20y+x²

E) (a+3x)² =

a²+2.a.3x+(3x)² =

a²+6ax+9x²

F) (xy+5)² =

(xy)²+2.xy.5+5² =

x²y²+10xy+25

G) (3m²+4n)² =

(3m²)²+2.3m².4n+(4n)² =

9m⁴+24m²n+16n²

H) (xy+p³)² =

(xy)²+2.xy.p³+(p³)² =

x²y²+2xyp³+p⁶

I) (xy-5)² =

(xy)²-2.xy.5+5² =

x²y²-10xy+25

J) (10x-0,1)² =

(10x)²-2.10x.0,1+(0,1)² =

100x²-2x+0,01
