Question

State how many imaginary and real zeros the fuction has. f(x)=x^5+7x^4+2x^3+14x^2+x+7

Answer 1

hint : write together the even powers of x ..and rest separately..

Answer 2

7x^4+14x^2 and then x^5+2x^3+x+7?

Answer 3

actually 7 = 7x^0
so thats also an even power..

Answer 4

what i mean is
(7x^4 + 14x^2 +7) + (x^5 + 2x^3 + x)

now take some terms common..
