Question

If α and β are the zeroes of the quadratic polynomial x
2 +5x+8, then the value of
α+ β is equal to :
(a) 5 (b) -5 (c) 8 (d) -8

Answer 1

Answer:

(k – 1)² + kx + 1

One zero is – 3, so it must satisfy the equation and make it zero.

∴ (k- 1) (- 3)² + k(-3) + 1 =0

⇒ 9k – 9 – Ik + 1 = 0

⇒ 6k – 8 = 0

⇒ k = \frac{8}{6} = \frac{4}{3}
