Ch-2 : Polynomials 1. A quadratic polynomial, whose zeores are -4 and -5, is(a) x² - 9x + 20(b) x² + 9x + 20(c) x² - 9x - 20(d) x² + 9x - 202. If one zero of the quadratic polynomial x² + 3x + k is 2, then the value of k is(a) 10(b) -10(c) 5(d) -53. Given that two of the zeroes of the cubic poly-nomial ax3 + bx² + cx + d are 0, the third zero is4. The number of polynomials having zeroes as -2 and 5 is (a) 1(b) 2(c) 3(d) more than 35. The zeroes of the quadratic polynomial x² + px + p, p ≠ 0 are(a) both equal(b) both cannot be positive(c) both unequal(d) both cannot be negative6. If x3 + 11 is divided by x² – 3, then the possible degree of remainder is(a) 0(b) 1(c) 2(d) less than 27. What is the number(s) of zeroes that a cubic polynomial has/have:(a) 0(b) 1(c) 2(d) 38. If p(x) is a polynomial of at least degree one and p(k) = 0, then k is known as(a) value of p(x)(b) zero of p(x)(c) constant term of p{x)(d) none of these9. If graph of a polynomial does not intersects the x-axis but intersects y-axis in one point, then no. of zeroes of the polynomial is equal to(a) 0(b) 1(c) 0 or 1(d) none of these10. A polynomial of degree n has(a) only 1 zero(b) at least n zeroes(c) at most n zeroes(d) more than n zeroes11. The constant term in polynomial having zeroes as -2, -2 and 5 is -(a) -2(b) -4(c) -20(d) 20​
