Answer:
12x-30 is the answer simplified
Step-by-step explanation
theres no much of a process
The polynomial functions A) and C) have a leading coefficient of 3, but C) has a lower degree.
f ( x ) = 3 x² - 21 x + 30
3 ( x² - 7 x + 10 ) = 3 ( x² - 5 x - 2 x + 10 ) =
= 3 ( x ( x - 5 ) - 2 ( x - 5 )) = 3 ( x - 2 ) ( x - 5 ) = 0
x = 2 and x = 5 ( roots )
Answer:
C ) f ( x ) = 3 x² - 21 x + 30
Answer:
zero
Step-by-step explanation:
the factors theorem state that if P(a)= 0 for a polynomial then x-a is a factor of the polynomial P(x)
Answer:
-1/2
Step-by-step explanation:
Answer:
100°
Step-by-step explanation:
sum of two interior angles in a triangle that is not adjacent to exterior angle is equal to that exterior angles
so
x° + 50° = 150°
x = 100
