A polynomial f(X) has degree 10.Then the maximum and minimum numbers of terms thatf(x) may have are(a) 11 and 1(b) 10 and 1(C) 10 and 2(d) 11 and 102. If each of the last two terms of the polynomial2x3 + 5x2 – 9x + 10 is increased by d so that theresulting polynomial has 1 as its zero, then thevalue of d is equal to(b) -1(c) 2 (d) -4(a) 13. The numbers to be subtracted from the polynomial x^4 + 2x^3 - 3x^2 + 5 so that -3 become it's zero, isa) -5 C) 1b) 5 d) 44. 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 toa) -2 C) 3b) -1 d) 15. X - 2 is a factor of the polynomiala) x^3 - 2x^2 + 3x - 6b) x^3 + 2x^2 - 3x - 6C) x^3 + 2x^2 - 3x - 6d) x^3 + 2x^2 + 3x + 6( class 9) |
