anyone know how to factor x^2+x+4?

Question

anonymous · Answer

if im not wrong its prime!

adunb8 · Answer

? why are you asking about $$x^4?$$

anonymous · Answer

Sorry, misread your question. 

It cannot be factor.

how so?

oh sorry this is actually linear algebra question using cauchy euler equation

anonymous · Answer

Use the quadratic formula by plugging in the variables from the given equation.
So taking your given equation..
$$x ^{2}+x+4$$
a=1
b=1
c=4
according to... $$ax ^{2}+bx+c = 0$$

Plug your numbers accordingly and you will get your answer when you set to zero.

$$\frac{ -b \pm \sqrt{b ^{2}-4ac} }{ 2a }$$

You should get...

$$\frac{ -1+\sqrt{15} }{ 2 },\frac{ -1-\sqrt{15} }{ 2 }$$

You can't factor this equation.

the trinomial cannot be factored. expression that cannot be factored is called prime.
