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

The number of roots for  equation is 4 .

Step-by-step explanation:

Here, the given function polynomial is :

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 is 4 .

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
