Question

What is the positive solution to the equation 2x^2+25=73

Answer 1

`x=√(24)`

Explanation:

2x^2+25=73

Subtract 25 from both sides:

2x^2=48

Divide both sides by 2:

x^2=24

Square both sides:

`\sqrt{x^(2) } =√(24)`

`x=√(24)`

Answer 2

2x^2+25=73
2x^2=73-25
2x^2=48
Now divide both sides by two
x^2=48/2
√x^2= √24
The square root cancels the squared so
x= √24
OR
x=2√6
