1. Check whether the following are quadratic equations:
(i) (x+1)=2(x-3)
(ii) - 2r=(-2)(3-0)
(ii) (x-2)(x+1)=(1-1)(+3)
(iv) (6-3)(2x+1)= x(x + 5)
(v) (2x - 1)(x-3) = (x + 5)(x - 1) (vi) 2+ 3+1 = ( - 2)
(vii) (x+2) = 2x (r2 - 1)
(viil).-4r-x+1=(x - 2)​

Answer:

  1. (x+1) = 2(x-3)
  • (x+1) = 2x-3
  • x+1 = 2x-3
  • 1+3= 2x+x
  • 4= 3x
  • 4/3=x
