Question

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

Answer 1

Answer:

(i) (x+1)  

2

=2(x−3)

(ii) x  

2

−2x=(−2)(3−x)

(iii) (x−2)(x+1)=(x−1)(x+3)

(iv) (x−3)(2x+1)=x(x+5)

(v) (2x−1)(x−3)=(x+5)(x−1)

(vi) x  

2

+3x+1=(x−2)  

2

 

(vii) (x+2)  

3

=2x(x  

2

−1)

(viii) x  

3

−4x  

2

−x+1=(x−2)
