Question

check whether 2 + under root 3 is a zero of x square minus 4 under root 3

Answer 1

Hello friend......☺

Here is your solution......_________

♦ Given to check whether 2 + √3 is a zero of
${x}^{2} - 4 \sqrt{3}$
So, on putting the value of x = 2 + √3 in the given polynomial we get,
=> ( 2 + √3)^2 - 4√3
=> 4 + 3 + 4√3 - 4√3
=> 7

Hence, we get a value that is equal to 7.
So, 2 + √3 is not a zero of the given polynomial.

Thanks....☺
