Question

____ is the remainder when quadratic polynomial 3x²-4x²+12 is divided by x-2 (Hint: Use Long division method, I've tried so many times but still the answer didn't came Help me fellows!!)​

Answer 1

Step-by-step explanation:

2x−1=0⇒x=

Answer 2

Answer:

x-2=0

x=2

3X2² -4X2²+12

3X4 -4X4+12
