Question

6x^2=726

`6x^2 = 726`
​

Answer 1

`6 {x}^(2) = 726 \\ \frac{6 {x}^(2) }{6} = (726)/(6) \\ {x}^(2) = 121 \\ x = √(121) \\ x = 11`

Answer 2

`x=11`

Explanation:

Step 1: Divide both sides by 6

`6x^2 / 6 = 726 / 6`

`x^2 = 121`

Step 2: Square root both sides

`√(x^2) = √(121)`

`x = 11`

Answer:
`x=11`
