Since is a factor, by factor theorem, , where
So ...solve it you will get your p
Since is a double root, so is a factor, get the other quadratic factor by either long division, comparison or synthetic division. You will get
a function is defiend by the following rule:
f (x) is
0 if x lesser than/equal to -3
-1 if -3<x<0
x if x is greater then or equal to 0
find i) F (-3) + f (-2) + f (2)
ii) f (a ^2)
another question:
4 ^ (x+1)/ ( 4 ^(x + 2) – 4 ^ (x) )
and another.
x-1 is a factor of x ^ 3 - (2 X ^ 2) + px + 6
find the value of P
and another
fully factorise the polynomial P(X) = X ^4 - 7x^3 + 12x^2 + 4x -16
given that x = 2 is a double root of P(x)
