Answer 1

òoooooooooooooķkkkkkkkkkkkkkkkkķ

Answer 2

Answer:

(2x² + 5)(2x + 3)(2x - 3)

Step-by-step explanation:

Given Equation is 8x⁴ + 2x² - 45

Let x² = u.

= 8u² + 2u - 45

= 8u² - 18u + 20u - 45

= 2u(4u - 9) + 5(4u - 9)

= (2u + 5)(4u - 9)

= (2x² + 5)(4x² - 9)

= (2x² + 5)[(2x²) - (3)²]

= (2x² + 5)(2x + 3)(2x - 3).

Hope it helps!
