Answer 1

Resposta:

a) (3a + 4b)2

$9a^{2}+24ab +16b^{2}$

b) (5x + 3y)2=

$25x^{2} +30xy+9y^{2}$

c) (10a + 7b)2=

$100a^{2} +140ab+49b^{2}$

d) (7c + 4d)2=

$49c^{2} +56cd+16d^{2}$

e) (8x + 12y)2=

$64x^{2} +192xy+144y^{2}$

f) (6a - 2b)2=

$36a^{2} -24ab+4b^{2}$

g) (12x - 15y)2=

$144x^{2} -360xy+225y^{2}$

h) (9a - 8b)2=

$81a^{2} -144ab+64b^{2}$

i) (7x - 4y)2=

$49x^{2} -56xy+16y^{2}$

j) (15a - 2b)2=

$225a^{2} -60ab+4b^{2}$

k) (3a - 5b) (3a + 5b)=

$9a^{2} +25b^{2}$

l) (6x + 2y) (6x - 2y)=

$36x^{2} -4y^{2}$

m) (16a + 8b) (16a - 8b)=

$256a^{2} -64b^{2}$

n) (20a + 3b) (20a - 3b)=

$400a^{2} -9b^{2}$

o) (17x - 4y) (17x + 4y)=

$289x^{2} -16y^{2}$
