Question

Check whether (x-3)(2x+1)=x(x+5) is a quadratic equation or not

Answer 1

Answer:

Not a quadratic equation

Step-by-step explanation:

∴ (x – 3) (2x + 1) = x(x + 5) is a quadratic equation. ∴ (2x – 1) (x – 3) = (x + 5) (x – 1) is a quadratic equation. Since 7x – 3 is a linear polynomial. ∴ x2 + 3x + 1 = (x – 2)2 is not a quadratic equation
