Answer:

i hope this helps

Step-by-step explanation:

2$x^{2}$ -16=0

+16        +16

2$x^{2}$ =16

÷2    ÷2

$x^{2}$ = 8

$\sqrt{x^{2} }$= $\sqrt{8}$

x= $\sqrt{8}$

-5$x^{2}$ +9=0

-9          -9

-5$x^{2}$=-9

÷-5   ÷-5

$x^{2}$ =1.8

$\sqrt{x^{2} }$= $\sqrt{1.8}$

x= $\sqrt{1.8}$

6$x^{2}$ -15=27

+15        +15

6$x^{2}$ =42

÷6   ÷6

$x^{2}$ =7

$\sqrt{x^{2} }$= $\sqrt{7}$

x=$\sqrt{7}$
