Question

x/5-3=x² is it a quadratic equation​

Answer 1

- x^2 + x/5 - 3 = 0

YES IT IS A QUADRATIC EQUATION

Answer 2

Answer:

Option ( B ) is correct

Step-by-step explanation: If degree of an equation is 2 then it is

called quadratic equation .

A ) 5/( x - 3 ) = x²

5 = x²( x - 3 )

5 = x³ - 3x

degree = 3

2) x( x + 5 ) = 2

x² + 5x = 2

degree = 2

Quadratic equation.

C ) n - 1 = 2n

-1 = n

degree = 1

Linear equation .

D ) 1/x² ( x + 2 ) = x

1/( x³ + 2x² ) = x

1 = x( x³ + 2x² )

1 = x⁴ + 2x³

degree = 4
