Question

check whether the following are quadratic equations ( x_3)(2x+1)=x(x+5)​

Answer 1

Answer:

Yes, it is a quadratic equation.

Step-by-step explanation:

(x-3) (2x+1)=x(x+5)

2x^2 + x - 6x -3 = x^2 + 5

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

x^2 - 10x - 3 = 0

Hence proved, this is a quadratic equation.
