Question

alguém me ajuda nessas questões
(a) (x + 1)² =
(c) (2x + 3y) =
e) (2ab + 1)2 =
g) (a b + ab) =
b) (2x + 3) =
d) (5a + x) =
f) (x² + y)2 =
h) (3a + 2bc)² =
(i) (3x
+ y)² =
1) (6x + 1) =​

Answer 1

Explicação passo-a-passo:

a) (x+1)² = (x)² +2.x.1+(1)²

x²+2x+1²

c) (2x+ 3y)²= (2x)² +2.2x.3y+(3y)²

4x² + 12xy+ 9y²

e)(2ab+1)²= (2ab)²+2.2ab.1+(1)²

4ab² + 4ab+ 1²

g)(ab+ab) =(ab)²+2.ab.ab+(ab)²

ab²+ 2ab²+ab²

b)(2x+3) = (2x)²+2.2x.3+(3)²

4x²+ 12x+ 9

d)(5a+x)= (5a)²+2.5a.x+(x)²

25a²+10ax+x²

f)(x²+y)²= (x²)²+2.x².y+(y)²

x⁴+ 2x²y+y²

h)(3a+2bc)²= (3a)²+2.3a.2bc+(2bc)²

6a²+12abc+4bc

i)(3x+y)= (3x)²+2.3x.y+(y)²

9x²+ 6xy+y²

1)(6x+1)²= (6x)²+2.6x.1+(1)²

36x²+12x+ 1²

espero ter ajudado ;)
