Question

check whether (x-2) (x-3)= (x+1) (x-1) is a quadratic equation (or) not jusitify​

Answer 1

Answer:

It's linear equation.

Step-by-step explanation:

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

by using Identity( a-b)(a+b) = a²-b²

x(x-3)-2(x-3) = x²-1

x²-3x-2x+6 = x²-1

-5x+6+1 = 0

-5x+7 = 0

since degree of polynomial is not 2.

Therefore, it is not a quadratic equation.
