Find the number of roots for each equation.<br> 5. 5x4 + 12x3 – x2 + 3x + 5 = 0

pav-90 [236]

Answer:

The number of roots for equation $5x^4 + 12x^3 – x^2 + 3x + 5 = 0$ is 4 .

Step-by-step explanation:

Here, the given function polynomial is :

$P(x) : 5x^4 + 12x^3 – x^2 + 3x + 5 = 0$

The Fundamental Theorem of Algebra says that a polynomial of degree n will have exactly n roots (counting multiplicity).

Now here, the degree if the polynomial is 4 (highest power of variable x).

So, according to the Fundamental Theorem, the given polynomial can have AT MOST 4 roots, counting Multiplicity.

Hence, the number of roots for equation $5x^4 + 12x^3 – x^2 + 3x + 5 = 0$ is 4 .
