Question

. If and are the zeros of the quadratic Polynomial
P(x) = 4x2
-5x-1, find the value of
2+2
.

Answer 1

Step-by-step explanation:

One root is negative of others. So, the sum of the roots must be zero.

For any quadratic equation Like : ax2 + b x + c = 0

The sum of roots is given by – b/a So, in this equation : 4x2 − 8ka − 9b

= − 8k & a = 4

So, 0 = – b/a

− (−8 k) /4 = 0

2 k = 0 ⇒ k = 0
