Q4 of 227 Page 114

If one zero of the polynomial p(x) = (k + 4)x2 + 13x + 3k is reciprocal of the other, then k is equal to

Given: A Quadratic equation p(x) = (k + 4)x2 + 13x + 3k

Required: To find the value of k


Let the roots of the given Quadratic equation be: and


∴ Product of roots of the given Quadratic equation is


We know that, Product of roots of a given Quadratic equation is


∴


⇒


⇒ 3k = k + 4


⇒ 2k = 4


⇒ k = 2


∴ The value of k is 2


∴ Correct option is – Option (A)
