Question

Solve equation: 2x^2-50=0

Answer 1

`x=` ±
`5`

Explanation:

`2x^(2) -50=0`

`2x^(2) =50`

`x^(2) =(50)/(2)`

`x^(2) =25`

`x=√(25)`

`x=` ±
`5`

There are 2 solutions for x: 5 positive and 5 negative. If you square them they result in 25

Hope this helps

Answer 2

Given:

`2x^2-50=0`

To solve for x:

`\begin{gathered} 2x^2-50=0 \\ 2x^2=50 \\ x^2=25 \\ x=\pm5 \end{gathered}`

Hence, the solution is x=-5, 5.
