Answer:
(x + 1)(x - 1)(x² + 9)
Step-by-step explanation:
Factorise the following:
x⁴ + 8x² - 9

The factors of -9 that sum to 8 are 9 and -1.
So,
x²(x² + 9) - 1(x² + 9)
(x² - 1)(x² + 9)
x² - 1 = x² - 1²:
(x² - 1²)(x² + 9)
Factor the difference of two squares.
x² - 1² = (x + 1)(x - 1):
(x + 1)(x - 1)(x² + 9)
I think 1,200 mph. Maybe not. Hoped I got somewhere!
