Question

(i) 6+ x = x2
solve this quadratic equation ​

Answer 1

Answer:

x=2

Step-by-step explanation:

6+x=2x

6=2x+x

6=3x

6/3=x

x=2

Answer 2

Step-by-step explanation:

6+x-x^2=0

-(x^2-x-6)=0

x^2-3x+2x-6=0

x(x-3)+2(x-3)=0

(x+2) (x-3) =0

therefore,

x+2=0

x=-2

x-3=0

x=3

the value of x cannot be negative... therefore the value of x =3
