Question

y- 5 = 1 find y² - 1/y²​

Answer 1

y-5 = 1

y=6

$\frac{y {}^{2} - 1 }{y {}^{2} }$

$\frac{36 - 1}{36}$

$\frac{35}{36}$

Answer 2

Step-by-step explanation:

$y - 5 = 1$

$y = 1 + 5$

$y = 6$

${y}^{2} - \frac{1}{ {y}^{2} }$

putting the value y = 6.

${6}^{2} - \frac{1}{ {6}^{2} }$

$36 - \frac{1}{36}$

$\frac{1296 - 1}{36}$

$\frac{1295}{36}$

$35.97$
