Answer:
x = i and x = i
Step-by-step explanation:
Given
+ 6x² + 5 = 0
Using the substitution u = x², then
u² + 6u + 5 = 0 ← in standard form
(u + 1)(u + 5) = 0 ← in factored form
Equate each factor to zero and solve for u
u + 1 = 0 ⇒ u = - 1
u + 5 = 0 ⇒ u = - 5
Convert solutions back into terms of x
x² = - 1 ⇒ x = 
= i
x² = - 5 ⇒ x = 
= i
no i don't think so the answer will be (3,0)

Answer:
1. a ≥ -3 and a ≤ 3
I am assuming you mean to have an = sign as well
Step-by-step explanation:
|a| < =3
we get two solutions, one positive and one negative
remember to flip the inequality for the negative
a<=3 and a >= -3
