Hello,

could u plz help me out with this?

whatever I put after return, it does not display undefined as a keyword:

Modify the function `abTest`

so that if `a`

or `b`

are less than `0`

the function will immediately exit with a value of `undefined`

.

my code:

function abTest(a, b) {

// Only change code below this line

var c;

if(“a” < 0 || “b” < 0){

return c;

}

// Only change code above this line

return Math.round(Math.pow(Math.sqrt(a) + Math.sqrt(b), 2));

}

abTest(2,2);

```
**Your code so far**
```

```
// Setup
function abTest(a, b) {
// Only change code below this line
var c;
if("a" < 0 || "b" < 0){
return c;
}
// Only change code above this line
return Math.round(Math.pow(Math.sqrt(a) + Math.sqrt(b), 2));
}
abTest(2,2);
```

```
