Determine Whether the Given Values Are Solutions of the Equation

Question:

Determine whether the given values are solution of the given equation or not:

\[ x^2+x+1=0 \]

(i) \(x=0\)
(ii) \(x=1\)

Solution

A value of \(x\) is a solution of an equation if it makes the left-hand side equal to zero.

Checking \(x=0\)

Substitute \(x=0\) into the equation:

\[ 0^2+0+1 \]

\[ =1 \]

Since \(1 \ne 0\), \(x=0\) is not a solution.

Checking \(x=1\)

Substitute \(x=1\) into the equation:

\[ 1^2+1+1 \]

\[ =3 \]

Since \(3 \ne 0\), \(x=1\) is not a solution.

Answer

Neither \(x=0\) nor \(x=1\) satisfies the equation.

\[ \boxed{x=0 \text{ is not a solution and } x=1 \text{ is not a solution}} \]
