# Why we have to take value 1 of x

The question is here solved by hit and trial method

Questions involving degree more than 2 have to be solved using hit and trial method concerning the grade you are studying.

Usually integers should be put and checked.

Start by 0 and then +1 and -1

then +2 and -2 and so on.

Her when you will start hit and trial you will see that x=0 wont satisfy but x=1 will.

Hence x=1 is the solution.

You may try the following questions for practice

x

^{300}-3x+2

x=0 wont satisfy

x=1 will satisfy.

Hence x=1 is the solution.

Similarly x

^{3}+x

^{2}+x+1

x=0,1 wont satisfy

But x=-1 will

Hence x=-1 is the solution

Hope that helps

Cheers!!
