If one root of the equation

$x^{2} + tx + 98 = 0$ is twice the other, then find the values of

$t$ . Hence, find the roots of the equation.

[Note: Enter the answers from smallest number to greatest number]

$t =$ ,

[Note: Choose two possible roots]

$α = \pm 14, β = 7$
$α = -14, β = -7$
$α = 14, β = \pm 7$
$α = -14, β = 7$
$α = 14, β = -7$
$α = 14, β = 7$
