Question

check whether the following is quadratic equation (x-2)(x+1)=(x-1)(x+3)​

Answer 1

The equation is not a quadratic equation because it's highest power of x is not 2

Step-by-step explanation:

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

x^2+x-2x-2 = x^2+3x-x-3

x^2-x-2 = x^2 +2x - 3

-x-2 = + 2x -3

-x-2-2x+3 = 0

-3x+1 =0

Answer 2

Answer:

x( x+1)-2(x+1)

x2+ x -2x-x=x2-2x
