Question

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

Answer 1

if im not wrong its prime!

Answer 2

? why are you asking about \[x^4?\]

Answer 3

Sorry, misread your question.

It cannot be factor.

Answer 4

how so?

Answer 5

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

Answer 6

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...

\[\frac{ -1+\sqrt{15} }{ 2 },\frac{ -1-\sqrt{15} }{ 2 }\]

Answer 7

You can't factor this equation.

Answer 8

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