I recently tried to factor this but i cant because its has no real root but i need solution i will pass it in my teacher on monday please help me
Since it does not have real roots you will not be able to factor it in terms of real numbers.
In mathematics, you don't understand things. You just get used to them.
I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.
