Question

√7,-√7are zeroes of a quadratic polynomial then find the quadratic polynomial​

Answer 1

$x = \sqrt{7} and \: - \sqrt{7}$

$(x - \sqrt{7} )(x + \sqrt{7} )$

$x {}^{2} - 7$

Answer 2

Answer:

let α=√7 and β= -√7

α+β= -b/a

a+β = √7+(-√7)

= √7-√7 =0

αβ = c/a

αβ = √7×-√7

= -7

so the polynomial is

x²-(α+β)x+αβ

x²-0x+(-7)

x²-7
