Heya mate,
Here is your answer,. ⬇️⬇️
___________
(x - 8)(480/x + 3) = 480
=> 480 + 3x - 3840/x - 24 = 480
=> 3x - 3840/x = 24
=> 3x^2 - 3840 = 24x
=> 3x^2 - 24x - 3840 = 0
=> x^2 - 8x - 1280 = 0
=> x^2 - 40x + 32x - 1280 = 0
=> x(x - 40) + 32(x - 40) = 0
=> (x - 40)(x + 32) = 0
=> x = 40, (-32)
➡️ Hence, x = 40, ( - 32)

Hope this helps,.
