Answer:

(4x + 1)(x² - 2)

Step-by-step explanation:

Given

4x³ + x² - 8x - 2 ( factor the first/second and third/fourth terms )

= x²(4x + 1) - 2(4x + 1) ← factor out (4x + 1) from each term

= (4x + 1)(x² - 2)

Answer:

The value of k is 1.

Step-by-step explanation:

x – 1 is a factor of f(x)

This means that:

x - 1 = 0

x = 1

That means that when $x = 1, y = 0$ . We use this to find the value of k.

f(x) = 3x^3 - 4x + k

$3*1^3 - 4(1) + k = 0$

$3 - 4 + k = 0$

$k = 1$

The value of k is 1.

djyliett [7]

Answer: 231

Explanation:

Liwen Celina

5x 6x

5x - 21 = $(\frac{2}{3})$ 6x

5x - 21 = 4x

-4x +21 -4x +21

x = 21

Liwen: 5x = 5(21) = 105

Celina: 6x = 6(21) = 126

Total: 231
