Question

by completing whole square method :
y^2-2y+24=0..

Answer 1

y = minus root 95 by 2 minus 1 /2
hope it helps you.

Answer 2

Given Equation is y^2 - 2y + 24 = 0

= > y^2 - 2y + 24 + (1)^2 - (1)^2 = 0

= > y^2 - 2y + 1 + 24 - 1 = 0

= > (y - 1)^2 = -24 + 1

= > (y - 1)^2 = -23.


Now,

(1)

$= \ \textgreater \ y - 1 = - \sqrt{23}$

$= \ \textgreater \ y - 1 = \sqrt{23} i$

$= \ \textgreater \ y = \sqrt{23} i + 1$

$= \ \textgreater \ y = 1 + \sqrt{23} i$



(2)

$= \ \textgreater \ y - 1 = - \sqrt{-23}$

$= \ \textgreater \ y - 1 = - \sqrt{23} i$

$= \ \textgreater \ y = 1 - \sqrt{23} i$



Hope this helps!
