Question

check whether the following are quadratic equations? i) (x-2) (x+1) =(x-1) (x+3)​

Answer 1

Answer:

No, it is not an quadratic equation

Step-by-step explanation:

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

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

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

x^2-x^2-x-2x-2+3=0

-3x+1=0

3x-1=0

No, it is not an quadratic equation.
