Find the limit (enter 'dne' if the limit does not exist)
hint: rationalize the denominator.

lim(x, y)→(0,0)(−2x^2−6y^2)/sqrt(−2x^2−6y^ 2+1)-1

Step-by-step explanation:

We need to first simplify the expression using rationalization(i.e. if a square root term exists in the denominator, then multiply and divide the whole expression by the denominator(but the change the sign of its middle term))

here, we need to find:

first we'll rationalize our expression:

this is our simplified expression, now we can apply our limits:

the limit does exists and it is 2.

50-60=10

step-by-step explanation:

because that’s us why
