We have,

f(x) = 2x⁴-6x³+2x²-x+2 and g(x) = x+2

Therefore, by remainder theorem when f (x) is divided by g (x) = x – (-2), the remainder is equal to f (-2)

Now, f(x) = 2x⁴-6x³+2x²-x+2

f (-2) = 2 (-2)⁴ – 6 (-2)³ + 2 (-2)² – (-2) + 2

= 2 * 16 + 48 + 8 + 2 + 2

= 32 + 48 + 12

= 92

Hence, required remainder is 92.
