Question

How many zeros are in f(x) = 3x^4 + x + 2

i know its 4... but i dont know how to solve the question
so please help me solve the question and show how there are 4 zeroes

Answer 1

The power of the polynomial determines the number of zeroes it has in this case power is 4 so 4 zeroes. Whereas in 5^3+4 it has 3 zeroes as its power is 3. U can find the zero by trial and error method.

Hope this helps.
