Question

HURRY I NEED HELP!!!!!

Answer 1

Answer:

• Both have 4 imaginary roots

Step-by-step explanation:

1)

• (x^2 + 9)(x^2 + 6) = 0

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)

• (x^2 + 7)(x^2 + 5) = 0

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
