ANSWER
The correct answer is D.
EXPLANATION
If we express the monomial,
as product of primes, we obtain:
If we express the monomial
as product of primes we obtain:
The least common multiple of these two binomials is the product of the highest powers of the common factors.
The LCM is
Therefore the correct answer is D.
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
