Answer:
u² – 11u + 24 = 0 where u = (x² – 1)
Explanation:
Given the equation;
(x² – 1)² – 11(x² – 1) + 24 = 0
We can let;
u = x² - 1
Substituting the value of u in the equation we get;
(u)² - 11 (u) + 24 = 0
u²- 11u + 24 = 0
Therefore;
The quadratic equation that is equivalent to the equation is;
u² – 11u + 24 = 0 where u = (x² – 1)
