Question

If one of the zeros of the polynomial x×x×x+ax×x+bx+c is -1,then find the product of the other two zeros​

Answer 1

Answer:

given one of the zeros of quadratic polynomial (k-1)x2+kx+1 is -3

so when we substitute -3 in the polynomial ,we get 0

→(k-1)(-3)²+k(-3)+1=0

→9k-9-3k+1=0

→6k-8=0

→k=8/6=4/3
