d) ( 8+x )² =
e) (3a +4b )² =​

Answer 1

Explicação passo-a-passo:

1- a) ( x +6 )²

x²+2x.6+6²

x²+12x+36

b) (a+5)²

a²+2a.5+5²

a2+10a+25

c) (2x+3)²

(2x)²+2.2x.3+3²

4x²+2.2x.3+3²

d) (8+x)=

8x+1x

(8x+1)x

9x

e) (3a+4b)²

(3a)²+2.3a.4b+(4b)²

9a²+2.3a.4b+(4b)²

9a²+24ab+(4b)²

9a²+24ab+16b²
