D)33xy² - 44x²y
E)4ax³ + 6a²x² + 4a³x²
F)45a5y⁴ - 75a⁴y5 + 105a³y6

Answer 1

vamos lá...

Fatorar : fator comum em evidência

a)  
x⁴+3x³+x²=x²(x²+3x+1)
b)
x³y²-x²y³=x²y²=(x-y)
c)
14xy-21xz=7x(2y-3z)
d)
33xy²-44x²y=11xy(3y-4x)
e)
4ax³+6a²x²+4a³x²=2ax²(2x+3a+2a²)
f)
45a⁵y⁴-75a⁴y⁵+105a³y⁶=15a³y³(3a²y-5ay²+7y³)
