Answer

(x²)² + 5(x²) - 6

Option B is correct.

Then, when we make the substitution, a = x², the expression becomes

(a)² + 5(a) - 6

Option A is correct.

Step-by-step explanation

The expression is

x⁴ + 5x² - 6

we can then put this in quadratic expression form

(x²)² + 5(x²) - 6

Option B

Then, when we make the substitution, a = x², the expression becomes

(a)² + 5(a) - 6

Option A

Hope this Helps!!!
