Question

T square -t -4 =0 solve this quadratic equation

Answer 1

t²-t-4=0

Here factorisation through factors of constant is not possible.

we should solve through quadratic formula.

t=

$\frac{ - b +or - \sqrt{ {b}^{2} - 4ac } }{2a}$

=[1+_√1-4.1.(-4)]÷2=1+_√17/2=1/2+_√17/2

•°•t=1/2+√17/2 or 1/2-√17/2

Hope it helps.
