What are all of the real roots of the following polynomial? f(x) x^4-24x^2-25

x = ±5

Step-by-step explanation:

We are given the following polynomial function and we are to find all of its real roots:

Let so we can now write it as:

Factorizing it to get:

Substitute back to get:

The quadratic factor has only complex roots. Therefore, the real roots are x = ±5.

The real roots are  ±5

Step-by-step explanation:

It is given that,

f(x) = x^4 - 24x^2 - 25

To find the real roots

Let x^4 - 24x^2 - 25 = 0 (1)

Take y = x^2

Then eq (1) becomes,

y^2 - 24y - 25 = 0

By using splitting method we can write,

y^2 + y - 25y - 25 = 0

y(y + 1) - 25(y +1) = 0

(y + 1)(y - 25) = 0

(x^2 + 1 )(x^2 - 25) = 0

From (x^2 + 1 ) we get complex roots

x^2 = -1

x = √-1

x - 25 = 0 we get real roots

x = 25

x = ±5

Therefore the real roots are  ±5
