1) (x+2)^2=2(x-3)
(x^2+4+4x)=2x-6
x^2+(4-2)x+4+6=0
x^2+2x+10=0
=>this is a quadratic eq
2) x^2-2x=(-2)(3-x)
x^2-2x=-6+2x
x^2-4x+6=0
=>this is a quadratic equation
(x^2+4+4x)=2x-6
x^2+(4-2)x+4+6=0
x^2+2x+10=0
=>this is a quadratic eq
2) x^2-2x=(-2)(3-x)
x^2-2x=-6+2x
x^2-4x+6=0
=>this is a quadratic equation
