Question

x+3 is one of the factor of polynomial (k-1)x^2+kx-3 then the value of k is​

Answer 1

Step-by-step explanation:

● Sol : - let (k-1)^2+kx-3 equation 2

X + 3 = 0

then,

x = -3

putting the value of x in equation 1

》》》( k - 1 ) × 9 + (-3k) - 3 = 0

》》》 9k - 9 - 3k -3 = 0

》》》 6k - 12 = 0

》》 k = 12/6 = 2
