Answer 2

Resposta:

a- $4x^{2}$$+12x+9$

b- $36x^{2}$$+60x+25$

c- $16x^{4}$+$48x^{3}$+$36x^{2}$

d- $49x^{4} +42x^{3} +9x^{2}$

e- $81x^{6} +126x^{5} +49x^{4}$

f- $x^{2} .(8x+9)$

g- $49x^{8}+14x^{7}+x^{6}$

h- $x^{4} +2x^{3} +x^{2}$

Explicação passo-a-passo:

a- $2x^{2} +2.2x.3+3^{2} =4x^{2} +12x+9$

b- $6x^{2} +2.6x.5+5^{2} = 36x^{2} +60x+25$

c-$(4x^{2})^{2} +2.4x^{2} .6x+6x^{2}= 16x^{4}+48x^{3} +36x^{2}$

d-$(7x^{2})^{2} +2.7x^{2} .3x+3x^{2} =49x^{4} +42x^{3} +9x^{2}$

e- $(9x^{3})^{2} +2.9x^{3} .7x^{2}+(7x^{2}) ^{2} =81x^{6} +126x^{5} +49x^{4}$

f- $x^{2} .(8x+9)$

g-$(7x^{4})^{2} +2.7x^{4} .x^{3} +(x^{3} )x^{2} = 49x^{8}+14x^{7}+x^{6}$

h- $(x^{2} )x^{2} +2.x^{2} .x+x^{2} =x^{4} +2x^{3} +x^{2}$
