Is the square root of infinity still infinity?.
hram777 [196]
The square root of infinity is still infinity, or rather, undefined or indeterminate. For example, if you take the square root of a big number, you will still have a big number as a result, now if you make the number even bigger, the square root will also get bigger, now imagine what will happen if this number is infinite.

​​someone pls help meeeee!!!!!!<br>​​
GuDViN [60]

Step-by-step explanation:

y = y

x - 2 = 2x - 3 - 3x²

3x² + x - 2x = - 3 + 2

3x² - x = - 1

.

a = 3, b = -1, c = 0

.

\sf{x = \frac{-b \pm \sqrt{b^{2} - 4ac} }{2a} }

\sf{x = \frac{- (-1) \pm \sqrt{-1^{2} - 4 (0)} }{2(3)} }

\sf{x = \frac{ 1 \pm \sqrt{1 - 0} }{6} }

\sf{x = \frac{ 1 \pm \sqrt{1} }{6} }

\sf{x = \frac{ 1 + 1 }{6} }

\sf{x = \frac{ 2 }{6} }

\sf{x = \frac{ 1 }{3} }

.

Substitution :

y = x - 2

y = ⅓ - 2

y = ⅓ - 6/3

y = - 5/3

y = - 1 ⅔

.
