Question

Fatore:

a) x² + x + 1/4

b) x² + x/3 + 1/36

c) x

4 + 3x³ + x²

d) 45x

5y

4 – 75x4y

5 + 105x³y6

e) X³y² - x²y³​

Answer 1

x  + 3x³ + x² = x²( x² + 3x + 1)

-------------------------------------------------------------

x³y² - x²y³ = x²y²(x + y)

---------------------------------------------------------------

14xy - 21xz = 7x(2y - 3z)

-------------------------------------------------

33xy² - 44x²y = 11xy( 3y - 4x)  

------------------------------------------------

4ax³ + 6a²x² + 4a³x² = 2ax²(2x + 3a + 2a²)

---------------------------------------------------------

    5  4        4  5               6           4

45a y   - 75a y   + 105 a³y = 15a³y ( 3a²y³ - 5ay + 7y²)
