Answer 1

By hit and trial method put x=-1,

it satisfies the given equation.

Now dividing the given equation by x+1,we get remainder zero.

Use dividened=(divisor×quotient)+remainder

(x+1)(x^2-x-1)=0

solve quadratic,you will get x=(1+√5)/2 and (1-√5)/2

So, solutions are x=-1,(1+√5)/2 and (1-√5)/2.
