Answer:
- Both have 4 imaginary roots
Step-by-step explanation:
1)
1.
- x^2 + 9 = 0
- x^2 = - 9
- x = ± √-9
- x = ± 3i
2.
- x^2 + 6 = 0
- x^2 = -6
- x = ±√-6
- x = ± i√6
It has 4 imaginary roots and no real roots
2)
1.
- x^2 + 7 = 0
- x^2 = -7
- x = ± √7
- x = ± i√7
2.
- x^2 + 5 = 0
- x^2 = - 5
- x = ± √-5
- x = ± i√5
It has 4 imaginary roots and no real roots

Step-by-step explanation:
g(x)=2x+3
La derivada de un polinomio es la suma de las derivadas de sus términos. La derivada de cualquier término constante es 0. La derivada de ax
