Spoiler: Solution to previous:

Answer to that was -14.

Problem: lim x → 2 [(7x²-14x) / (2-x)]

If we substitute 2 into the equation: We get 0/0 which is indeterminate... so,

Step 1 (Factor): (7x²-14x) to get 7x(x-2).
Step 2 (Express): (2-x) as (-x+2) then factor the negative out to get -(x-2).

Now we have: lim x → 2 [7x(x-2) / -(x-2)]

Step 3 (Cross out): (x-2) from the numerator and denominator.

Now we have: lim x → 2 [7x / -1]...
which is lim x → 2 [-7x].

Step 4 (Plug in 2 from our limit of x): -7(2) = -14

Solve for y:
y = sqrt(2sin²(π/2) + 2cos²(π/2)) * e^πi

Note: π is pi
