If 2x3 – 4x2 + kx + 10 is divided by (x + 2), the remainder is 4. Find the value of k using remainder theorem. Please help :)

Vinvika [58]

The polynomial remainder theorem states that the remainder of the division of a polynomial $P(x)$ by $x-a$ is equal to $P(a)$ .

Therefore

$P(-2)=4\\2\cdot(-2)^3 - 4\cdot(-2)^2 + k\cdot(-2) + 10=4\\-16-16-2k=-6\\-2k=26\\k=-13$

Which of the following expressions are equivalent to - -a/b

riadik2000 [5.3K]

Answer:

B) $-\frac{a}{-b}$

Step-by-step explanation:

1. First, we have to know that two negatives equal positive.

2. Given the information above, $-\frac{-a}{b}$ can simplify to $\frac{a}{b}$ .

3. Let's go through each answer choice and see which one also simplifies to $\frac{a}{b}$ .

$\frac{a}{-b}$
$-\frac{a}{b}$

$-\frac{a}{-b}$
$\frac{a}{b}$

Therefore, the answer is B) $-\frac{a}{-b}$ .
