f(x) may have are
(a) 11 and 1
(b) 10 and 1
(C) 10 and 2
(d) 11 and 10
2. If each of the last two terms of the polynomial
2x3 + 5x2 – 9x + 10 is increased by d so that the
resulting polynomial has 1 as its zero, then the
value of d is equal to
(b) -1
(c) 2 (d) -4
(a) 1
3. The numbers to be subtracted from the polynomial x^4 + 2x^3 - 3x^2 + 5 so that -3 become it's zero, is
a) -5 C) 1
b) 5 d) 4
4. When x^3 + 4x^2 - 3x + b is divided by X - 2, then the remainder is the zero of another polynomial x^3 - 19x^2 + x - 19. Then the value of b is equal to
a) -2 C) 3
b) -1 d) 1
5. X - 2 is a factor of the polynomial
a) x^3 - 2x^2 + 3x - 6
b) x^3 + 2x^2 - 3x - 6
C) x^3 + 2x^2 - 3x - 6
d) x^3 + 2x^2 + 3x + 6
