The polynomial ax3 + bx2 + x - 6 has (x+ 2) as a factor and leaves remainder 4 when divided by (x-2) Find the value of a and b.
a=2,b=0
a=1,b=1
a=0,b=2
a=7,b=5
A non-terminating but recurring decimal is
an integer
a natural number
a rational number
an irrational number
The factors of polynomial x3- 6x2 + 11x - 6 are
(x+1)(x+2)(x-3)
(x-1)(x+2)(x-3)
(x-1)(x-2)(x-3)
(x-1)(x-2)(x+3)
If a, a + 2, a + 4 are prime numbers, then the number of values of a is
One
two
three
more than three
C.
three
Given, a, a+2, a+4 are prime numbers.
1) If a= 2 (prime)
then 2, 4, 6 all are not prime numbers.
2) If a= 3 (prime)
then, 3, 5, 7 all are prime numbers.
3) If a =5
then, 5,7, 9 all are not primer numbers.
4) If a =7
then, 7, 9, 11 all are not prime numbers.
