t2=449

Solution for t2=449 equation:

t2=449

We move all terms to the left:

t2-(449)=0

We add all the numbers together, and all the variables

t^2-449=0

a = 1; b = 0; c = -449;
Δ = b2-4ac
Δ = 02-4·1·(-449)
Δ = 1796
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{1796}=\sqrt{4*449}=\sqrt{4}*\sqrt{449}=2\sqrt{449}$
$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-2\sqrt{449}}{2*1}=\frac{0-2\sqrt{449}}{2}
=-\frac{2\sqrt{449}}{2}
=-\sqrt{449}
$
$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+2\sqrt{449}}{2*1}=\frac{0+2\sqrt{449}}{2}
=\frac{2\sqrt{449}}{2}
=\sqrt{449}
