Answer:
4
Step-by-step explanation:
Dividend : 3x³ -10x² +13x - 6
Divisor : x - 2
To find remainder, we first find the zero of the Divisor
Step 1. Equate the divisor to zero
x - 2 = 0
Step 2. Obtain the value of the variable (x)
x = 2
Step 3. Replace the variable(x) in the Dividend with the value obtained
3(2³) - 10(2²) + 13(2) - 6
3(8) - 10(4) + 26 - 6
24 - 40 + 20
= 4
Step 5. The number which we get after replacing the variable with the zero of the divisor is the reminder.
The remainder is 4
