[Terjawab] A quadratic polynomial, whose zeroes are -4 and -5, is a) x² - 9x + 20 b) x² + 9x + 20 c) x² - 9x - 20 8. For p(x) = ax² + bx + c, sum of zeroes is equal to a) zero b) c/a c) -b/a 9. Assertion: √2 is an irrational number. Reason: A number is irrational if it cannot be expressed in the form p/q, where p and q are integers and q ≠ 0 a) Both A and R are true, and R is the correct explanation of A. b) Both A and R are true, but R is not the correct explanation of A. c) A is true, but R is false. d) A is false, but R is true. 10. Assertion: If α & β are the zeroes of the quadratic polynomial x² - 7x + 10, then α + β = 7 and αβ = 10. Reason: For a polynomial ax² + bx + c, sum of zeroes = -b/a, and product = c/a. a) Both A and R are true, and R is the correct explanation of A. b) Both A and R are true, but R is not the correct explanation of A. c) A is true, but R is false. d) A is false, but R is true. SECTION - B 11. Find the HCF & LCM of 12, 15, 21 by applying the prime factorization method. 12. Given that HCF(306, 657) = 9, find LCM(306, 657). 13. Find the sum and product of the polynomial 2x² - 9x + 4 = 0. 14. Find the zeroes of the quadratic polynomial x² - 2x - 8, and verify the relationship between the zeroes and its coefficients. 15.
