Question

5)which of the following is a quadratic equation? * A) 6x²=20-x³ B) 3/x-3=4x² C)x²(1/x-2)=7/2 D)5x+7=3x​

Answer 1

Answer:

B) 3/x-3=4x²

=> 3/x-3-4x²=0

=> 4x²-3/x-3=0 [writing in order]

since the equation is in the form of ax²+bx+c=0 and the highest power of x is 2 hence it is a quadratic equation
