You can put this solution on YOUR website!
Well, you can't solve this "equation" because it is not an equation! It's an expression.
In an equation, you must have an equals (=) sign.
Now if you meant to write:
4d%5E2-25+=+0 then you can solve this!
4d%5E2-25+=+0 Add 25 to both sides of the equation.
4d%5E2+=+25 Now take the square root of both sides.
2d+=+5 or 2d+=+-5 Divide these by 2.
d+=+5%2F2 or d+=+-5%2F2
