Solve for \( y \).

Try factoring first. If factoring is not possible or difficult, use the quadratic formula.

\[ y^2 - 10y + 23 = 0 \]

[y^2-10y+23=0\ y^2-10y+25-2=0\ (y-5)^2=2\ |y-5|=\sqrt2\ y-5=\sqrt 2 \vee y-5=-\sqrt2\ y=5+\sqrt2 \vee y=5-\sqrt2

To solve the equation y 2 − 10 y + 23 = 0 , we used the quadratic formula. The solutions are y = 5 + 2 ​ and y = 5 − 2 ​ . Since the discriminant is positive, there are two distinct real solutions.
