Question

5. Find the zeroes of the quadratic polynomial 5

2– 4 – 8x and verify the

relationship between the zeroes and the coefficient of the polynomial.​

Answer 1

Here,given polynomial is 52-4-8x= 48-8x

Equating the above polynomial with zero, we get,

48-8x=0

or 8(6-x)=0

or 6-x=0

or x=-6

Therefore x=-6 is the answer.
