Question

Pls answer question 4 i got an exam tomm . Love! Giving 20 points for this simple one

Answer 1

Answer:

x = 4a²/b², -3a²/b²

Step-by-step explanation:

Given Equation is a²b²x² - (4b⁴- 3a⁴)x - 12a²b² = 0

⇒ a²b²x² - 4b⁴x + 3a⁴x - 12a²b² = 0

⇒ b²x(a²x - 4b²) + 3a²(a²x - 4b²) = 0

⇒ (a²x - 4b²)(b²x + 3a²) = 0

⇒ a²x - 4b² = 0, b²x + 3a² = 0

⇒ a²x = 4b², b²x = -3a²

⇒ x = (4b²/a²), x = (-3a²/b²).

Hope it helps!
