Is polynomial y4 + 4y2 + 5 have zeroes or not?
Answers
Answer:
The polynomial y4 + 4y2 + 5 has no zero(s) because the roots are not real. Since the first term has a degree of 4, it cannot be possible because it is not in the form of a quadratic equation, hence no zeroes.
Answer:
No, the polynomial equation + 4y² + 5 does not have any zeroes.
Step-by-step explanation:
Given :- The given polynomial equation is + 4y² + 5 = 0.
To Find :- If the polynomial equation + 4y² + 5 = 0 have zeroes or not.
Solution :-
A polynomial equation is an equation formed with sum of variables, non-negative integers, exponents, and coefficients together.
The given polynomial equation + 4y² + 5 is of degree 4.
We know that, (a +b)² = a² + b² + 2ab
+ 4y² + 5 = 0
⇒ + 4y² + 4 + 1 = 0
⇒ (y² + 2)² + 1 = 0
The expression (y² + 2)² + 1 will not be zero for any value of y since the 1st term is a square.
Therefore, the polynomial equation + 4y² + 5 will not have any real roots.
