(a^2-1)x^2+(a-1)x+(a^2-4a+3)=0 find a and x

To solve for \(a\) and \(x\), let’s examine the quadratic equation:

\[
(a^2 - 1)x^2 + (a - 1)x + (a^2 - 4a + 3) = 0
\]

This equation has two unknowns: \(a\) and \(x\). We can approach this by examining conditions under which the quadratic has real roots. Here’s a step-by-step breakdown:

### Step 1: Analyze the Quadratic in Terms of \(x\)

The general form of a quadratic equation in \(x\) is:
\[
Ax^2 + Bx + C = 0
\]
where \(A = a^2 - 1\), \(B = a - 1\), and \(C = a^2 - 4a + 3\).

### Step 2: Apply the Discriminant Condition

For a quadratic equation to have real roots, its discriminant \(\Delta\) must be greater than or equal to zero:
\[
\Delta = B^2 - 4AC
\]
Plugging in the values for \(A\), \(B\), and \(C\), we get:
\[
\Delta = (a - 1)^2 - 4(a^2 - 1)(a^2 - 4a + 3)
\]
Expanding this and setting \(\Delta \geq 0\) will provide values for \(a\).

### Step 3: Solve for \(a\)

After solving for \(a\) with \(\Delta \geq 0\), substitute the values of \(a\) back into the original quadratic equation to find the values of \(x\).
