Question

If α and β are the zeroes of the quadratic polynomial f(x)= ax2+bx+c, then α-β=---

6. What term of AP 21, 42, 63, 84,… is 210?​

Answer 1

Answer:

If one of the zeroes of polynomial is

ax2+bx+c is -1, then product of other two

zeroes is:

(a) a + b

(b) - 1

(c) - c/a

(d) -b/a. plz answer this with proper explanation pls pls
