Question

Obtain all other zeroes of the polynomial 2x3 – 4x – x
2 + 2, if two of its zeroes
are √2 and -√2.

Answer 1

Explanation:

A.T.Q

√2 and. -√2 are the zeroes of the polynomial 2x^3 - 4x - x

√2 and -√2 can be written as (x - √2) and (x +√2)

Now

(x - √2) × (x + √2)

= x^2 - 2

Divide the polynomial 2x^3 - 4x - x by x^2 - 2

Then using 'splitting the middle term' on the quotient, you will get the other two zeroes

Answer 2

Answer:

I think it is 2 I hope it is help ful
