Answer:
A polynomial of degree 3 has 3 linear factors… (1): (x - i ) (x + i ) (x + a) . If any 2 factors are conjugate as here first 2 factors are conjugate with complex roots. So at least one root should be real.
Step-by-step explanation:
x = 10
Step-by-step explanation: 10/2 = 5 + 1 = 6
28.42 > 28.404
it is true
40% of 780 = 312.
780- (312+180)
= 288
X=5+h
