Question

Check whether (3-2x+x²) is a factor of (5x³-4x²+3x+18)​

Answer 1

Answer:

In order to check, we need to put x²-2x +3 =0 and find the values of x.and then we need to put the values of x in 5x³- 4x²+3x +18 . Here the values of x in x² - 2x +3 are not real, hence we cannot proceed further.
