Answer 2

Explanation:

`2(x+(3)/(4))^2-5=123`

1. Add 5 to both sides.

`5+2(x+(3)/(4))^2-5=123+5`

`2(x+(3)/(4))^2=128`

2. Divide both sides by 2.

`(2(x+(3)/(4))^2 )/(2)=(128)/(2)`

`(x+(3)/(4) )^2=64`

3. Take the square root of both sides.

`\sqrt[]{(x+(3)/(4))^2 } =\sqrt[]{64}`

`x+(3)/(4)=8`

4. Subtract
`(3)/(4)` from both sides.

`-(3)/(4)+x+(3)/(4)=8-(3)/(4)`

`x=8-(3)/(4)`

`x=((8)(4)-3)/(4)`

`x=(32-3)/(4)`

`x=(29)/(4)`
