Step-by-step explanation:
A] 5/X - 3 = x²
=> X² - 5/X +3 =0
therefore, this is a quadratic eqn.
B] x(x+5) = 4
=> x² + 5x = 4
=> x² + 5x -4 = 0
therefore, this is a quadratic eqn.
C] n-1 = 2n
=> n - 1 - 2n = 0
=> - 1 -n =0
=> -(n + 1) =0
=> n+1 =0
therefore, this is not a quadratic eqn.
D] 1/x²(x+2) =x
=> 1/x + 2/x² = x
=> 1/x + 2/x² - x =0
therefore, this is not a quadratic eqn.
I hope it will help you...
