Answer 2

Let's solve the equation step by step:

(x² - 1)(x² + 3) = (x² + 1)² + x

First, expand the left side of the equation:

x⁴ + 3x² - x² - 3 = (x² + 1)² + x

Now, simplify the left side by combining like terms:

x⁴ + 2x² - 3 = (x² + 1)² + x

Next, expand the right side:

(x² + 1)² = x⁴ + 2x² + 1

Now, substitute this expression back into the equation:

x⁴ + 2x² - 3 = x⁴ + 2x² + 1 + x

Now, let's simplify further:

x⁴ - x⁴ + 2x² - 2x² - 3 - 1 - x = 0

Now, combine like terms:

-4 - x = 0

Now, add x to both sides of the equation:

-4 = x

So, the solution to the equation is x = -4.
