Question

Q.1 No of zeros in the polynomial p(x)= x³+5x+4 are​

Answer 1

If it helps then only mrk me as BRAINLIEST

Step-by-step explanation:

Let a, B,y are the zeroes of polynomial p(x) such that a +B=0.

Then,

Sum

of zeros =

a+B+7= 5 0+y=5

y=5

Also,

Product of zeros =

aby = -80

-5a= -80

a= 16

α+4

Now,

a+B=0

Coefficient of a?

Coefficient of 23

Constant term

Coefficient of 3

B=74

Thus, zeros of the given polynomial are 4,-4,5.
