Question

fatore as expressões​

Answer 1

Resposta:

d) $\left(b+m\right)\left(x+m\right)$

e) $\left(b+3\right)\left(a^{2}+1\right)$

f) $\left(x+3\right)\left(x^{2}+2\right)$

Explicação passo-a-passo:

d) $m ^ { 2 } +mx+mb+bx \\ m\left(x+m\right)+b\left(x+m\right) \\ \left(x+m\right)\left(m+b\right)$

e) $3a ^ { 2 } +3+ba ^ { 2 } +b \\ 3\left(a^{2}+1\right)+b\left(a^{2}+1\right) \\ \left(a^{2}+1\right)\left(3+b\right)$

f) $x ^ { 3 } +3x ^ { 2 } +2x+6 \\ x^{2}\left(x+3\right)+2\left(x+3\right) \\\left(x+3\right)\left(x^{2}+2\right)$

espero ter ajudado, bons estudos! :)
