Factorize (x2 -0.7x+0.49) into two terms such that:  (x- something) (x- something)

 

I can see straight off that there are no real solutions to this.

There are imaginary solutions but you might not know about imaginary numbers yet.

 

look at the discriminant

\(\triangle=b^2-4ac=0.49-4*0.49<0\)

 

Hence there is no real roots so this cannot be factorised without using imaginary number :)

How can I factorize it using imaginary numbers?
