Question

If one of the zeroes of the quadratic polynomial ( – 1) 2 + + 1 is −3, then the value of k is​

Answer 1

Answer:

here is the answer:-

Given −3 is the zero of the polynomial (k−1) x2 +kx+1

So −3 must satisfy the equation (k−1)x2+kx+1=0

⟹(k−1)(−3)2

+k(−3)+1=0

⟹9(k−1)−3k+1=0

⟹9k−9−3k+1=0

⟹6k=8

⟹k=3upon4

Answer 2

Answer:

$f(x) = ( - 1) \times 2 + 1 = 0. \\ f( - 3) = - 2 + 1 = 0. \\ f( - 3) = - 1 = 0. \\ \\ hence \: f( - 3) = - 1 \: and \: f(0) = - 1.$
