Question

check it is quadratic equations (x-2)(x+1)=(x-1)(x+3)​

Answer 1

Answer:

Necessary conditions for quadratic equations is that: It must be of the form

ax²+bx+c where a=! 0

a=! Means a not eqal to zero..

Explanation:

First of all simplify it...

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

x²-x-2=x²+2x-3

Clearly here x² cancelled out ie do not follow above form hence not a quadratic equations...

Hope it helps...

Answer 2

Answer:

no, because it is not in the form of ax²+bx+c=0

Explanation:

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

x²-x-2 = x²+2x-3

3x-1 =0
