Question

if one of the quadratic Polynomial (K-1)x^2 + kx +1 is -3 then find the value of k​

Answer 1

Answer:

k–2)x² + kx +1

ONE OF ZEROES IS GIVEN (–2)

i.e. x =  ONE OF ZEROES IS GIVEN (–2)

i.e. x = –2.

PUT VALUE OF X IN GIVEN POLYNOMIAL WE GET THAT ,

(k–2)(–2)² + k(–2) + 1

4(k–2) – 2k +1 =0

4k –8 –2k +1 =0

2k –7=0

k=7/2.
