Hello sister ✌

Here's your answer friend,

⏩ Given : Two zeroes of P(x) = 3x4 - 12x³ + 5x² +16x -12 = 0 are -2/√3 or 2/√3.

Therefore,

[ X + 2/√3][X - 2/√3] = 0

[ (X)² - (2/√3)² ]

==> X² - 4/3


therefore,

on dividing P(x) by X² - 4/3 we get,

X² - 4/3 = 0

==> it can be written as 3x² - 4

Division is attached with a picture... ✌

on dividing p(x) by 3x² -4 we get,

x² -4x + 3 = 0

==> x² -3x -x + 3 = 0

==> x(x -3) -1( x - 3) = 0

==> (x - 1 )(x - 3) =0

==> x = 1 or x = 3

i. e. Zeroes of above the polynomial are 1, 3, 2/√3 and -2/√3.
