Find all real solutions. 3y² = 4 - y⁴ A) y = - 3, 4, 1 B) y = - 4, - 1 C) y = 1, - 1 D) y = 3, 1 E) y = 3, - 4

Question

Quizplus · Accepted Answer

Starting with the given equation:

3y + 2 = 4 - y + 4

Simplifying, we have:

4y + 2 = 8

Subtracting 2 from both sides:

4y = 6

Dividing both sides by 4:

y = 1.5

Therefore, the only real solution is y = 1, as none of the answer choices include 1. However, we can check that if we substitute y = 1 into the given equation, it does indeed satisfy the equation:

3(1) + 2(1) = 4 - 1(4) + 4

3 + 2 = 4 - 4 + 4

5 = 5

So the answer is (C) y = 1, -1.
