Answer:The algebraic expression that is equivalent to [(x - 1)²/(x² - x - 12)] * [(x² + x - 6)/(x² - 6x + 5)] is; (x² - 3x + 2)/(x² - 9x + 20)

How to solve algebraic fractions?

We are given the algebraic expression;

[(x - 1)²/(x² - x - 12)] * [(x² + x - 6)/(x² - 6x + 5)]

Now, let us simplify each of the quadratic equations;

(x - 1)² = (x - 1)(x - 1)

x² - x - 12 = (x + 3)(x - 4)

x² + x - 6 = (x + 3)(x - 2)

x² - 6x + 5 = (x - 1)(x - 5)

Thus, our original expression can now be rewritten as;

[(x - 1)(x - 1)/((x + 3)(x - 4))] * [(x + 3)(x - 2)/(x - 1)(x - 5)]

Looking at the expression above, we see that (x + 3 ) and (x - 1) will cancel out to give;

[(x - 1)/(x - 4)] * [(x - 2)/(x - 5)]

Multiplying out gives;

(x² - 3x + 2)/(x² - 9x + 20)
