factorising trouble

[Anthonyk2013]

I have this problem I need to factorise this before I can begin to do the problem.

6x²+5

I add in 0x for purpose of equation

So 6x²+0x+5

Cant sole this, any help to point me in right direction

6x²+5

That cannot be factored over the real numbers.
If you know how to use complex numbers it can be factored.

Found this problem intriquing.

Is (x-(5/6)i)(x+(5/6)i) correct?

 

[Quaid]

Is (x-(5/6)i)*(x+(5/6)i) correct?

:idea: You can check this yourself.

Multiply your factors together, and see whether you obtain the given quadratic polynomial.

It appears that the problem in red is different than the problem in blue.

What is the problem in blue?

:cool:

ok cool, did check

re-worked prob and got:

the quantity root six x plus root 5 i times the quantity root six x minus root five i

which checks
