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!
thanku so much
welcome
