d ) (2 x + y). 12x+y)=
e) (a+b)²=
f) (3x-7). (3 x - y) =
g) ( a-b )²=
h) ( a+b).( a-b)=

Answer 1

Resposta:

a) −$8x^{2}$ -2x + 15

b) $2x^{2}$ + xy − $y^{2}$

c) $3a^{2}$ + 8ab + $4b^{2}$

d) $24x^{2}$ + 14xy + $y^{2}$

e) $a^{2}$ + 2ab + $b^{2}$

f) $9x^{2}$ − 3xy − 21x + 7y

g) $a^{2}$ − 2ab + $b^{2}$

h) $a^{2}$ - $b^{2}$
