Question

Check whether x(2x+3)=x square+1 is a quadratic equation or not.
​

Answer 1

Step-by-step explanation:

x(2x + 3) = x² + 1

=> 2x² + 3x = x² + 1

=> 2x² + 3x - x² - 1 = 0

=> x² + 3x - 1 = 0

as coefficient of x ≠ 0, it is a quadratic equation

Answer 2

Step-by-step explanation:

Yes it is a quadratic equation .

x ( 2x+3) = x² + 1

2x² + 3x = x²+1

2x² - x². + 3x - 1 = 0

x² + 3x -1 = 0

Hence it is a quadratic equation
