Answer:

<em>It must have 4 roots</em>

Step-by-step explanation:

<u>Fundamental Theorem of Algebra</u>

One polynomial of degree n will have exactly n roots. The degree of a polynomial is the highest exponent of its variable. Some of the roots could be real, some could be imaginary (complex). If n is odd, at least one of the roots is real.

The polynomial given in the question is

H(x)=4x^{4} -5x^{3}+2x^{2}-x+5

has a degree of 4 (the highest exponent of x). According to the Fundamental Theorem of Algebra, it must have 4 roots

Evaluate.<br> 25/5+7-(4x3)
navik [9.2K]
Using PEMDAS, we know that we must solve what’s in the perentheses first so: 25/5 + 7 - (4x3) = 25/5 + 7-12. Next, we simplify 25/5 because that is division so now it is 5+7-12. Now you add 7 to 5 to get 12 and then subtract 12 so your answer is now zero.
