Question

fatore: a) x⁴+3x³+x² b) x³y²-x²y³ c) 14xy-21xz d) 33xy²-44x²y e) 4ax³+6a²x²+4a³x² f) 45a5y⁴-75a⁴y5+105a³y6

Answer 1

 4
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)
---------------------------------------------------------

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