Answer
$x=1.25$ or $x=1.2$
Work Step by Step
We use the quadratic formula with $a=1$, $b=-2.45$, and $c=1.5$:
$x^{2}-2.450x+1.500=0$
$x=\displaystyle \frac{-(-2.45)\pm\sqrt{(-2.45)^{2}-4(1)(1.5)}}{2(1)}=\frac{2.45\pm\sqrt{6.0025-6}}{2}=\frac{2.45\pm\sqrt{0.0025}}{2}=\frac{2.450\pm 0.05}{2}$.
So we have:
$x=\displaystyle \frac{2.45+0.05}{2}=1.25$
Or:
$x=\displaystyle \frac{2.45-0.05}{2}=1.2$
