The Total solution for NCERT class 6-12
A quadratic polynomial, the sum of whose zeroes is 0 and onezero is 3, is(a) x2 – 9(b) x2 + 9(c) x2 + 3(d) x2 – 3
(a) In a quadratic polynomialLet α and β be its zerosand α + β = 0and one zero = 33 + β = 0 ⇒ β = -3 .Second zero = -3Quadratic polynomial will be(x – 3) (x + 3) ⇒ x2 – 9
