Here is the right photo please help i need this before july 1st thank you

Answer 1

i hope this helps

Explanation:

2
`x^(2)` -16=0

+16 +16

2
`x^(2)` =16

÷2 ÷2

`x^(2)` = 8

`\sqrt{x^(2) }`=
`√(8)`

x=
`√(8)`

-5
`x^(2)` +9=0

-9 -9

-5
`x^(2)`=-9

÷-5 ÷-5

`x^(2)` =1.8

`\sqrt{x^(2) }`=
`√(1.8)`

x=
`√(1.8)`

6
`x^(2)` -15=27

+15 +15

6
`x^(2)` =42

÷6 ÷6

`x^(2)` =7

`\sqrt{x^(2) }`=
`√(7)`

x=
`√(7)`
