Question

8a⁴ - 32a³ + 16a²) ÷ 4a²
​

Answer 1

Step-by-step explanation:

8a⁴ - 32a³ + 16a²

4a²

= 4a(2a³ - 8a² + 4a). .....(taking 4a as a common)

4a²

= (2a³ - 8a² + 4a). ....(dividing by 4a)

a

= (2a² - 8a + 4). ..... (dividing by a)

now by solving this quadratic equation

we get- a = 4 + 2√2. OR. a = 4 -4√2
