To solve this problem, we’ll apply the remainder theorem, which states that the remainder of the division of a polynomial $P(x)$ by $x - a$ is equal to $P(a)$. Here, we need to evaluate $P(-3)$ for the polynomial: $P(x) = -2x^4 - 6x^3 + 4x^2 - 6.$

Step 1: Substitute $x = -3$ into $P(x)$

$P(-3) = -2(-3)^4 - 6(-3)^3 + 4(-3)^2 - 6$

Now, we’ll calculate each term separately.

1. $(-3)^4$: $(-3)^4 = 81$ So, $-2 \cdot 81 = -162$.

2. $(-3)^3$: $(-3)^3 = -27$ So, $-6 \cdot -27 = 162$.

3. $(-3)^2$: $(-3)^2 = 9$ So, $4 \cdot 9 = 36$.

4. Constant term $-6$: $-6 = -6$

Step 2: Combine all terms

$P(-3) = -162 + 162 + 36 - 6$ $P(-3) = 0 + 36 - 6$ $P(-3) = 30$

So, the remainder when $P(x)$ is divided by $x + 3$ is 30.

Step 3: Interpret the Quotient

The remainder theorem only gives us the remainder directly, not the quotient. However, if you're required to find the quotient explicitly, polynomial division or synthetic division would be used, which is a longer process. For now, based on the remainder theorem question, you only need to enter the remainder and the value of $P(-3)$.

Final Answers

• Quotient: Undefined directly from remainder theorem (requires polynomial division).
• Remainder: 30
• $P(-3)$: 30
