Answer

(x - 4)

Step by step explanation

To find the factors, plug in the x values in the given equation and see which value of x makes the equation equal to zero.

Here (x - 4) is a factor.

Therefore, x = 4

when we plug in x = 4 in the given expression, we get zero.

Let's check it out.

3(4)^3 + 8 (4)^2 - 87(4) + 28

192 + 128 - 348 + 28

348 - 348

The answer is (x - 4)

Thank you.

Given the coordinates A (5, 7, -2) and B (8, 3, 4) in 3d space, express AB as:

lys-0071 [83]

The vector AB is found by subtracting the coordinates of point B from the coordinates of point A => (8, 3, 4) - (5, 7, - 2)

(8, 3, 4) - (5, 7, - 2) = (3, - 4, 6)

=>

a) a 3 x 1 column =

| -4 |
| 6 |

b) xi + yj + zk

=> 3i - 4j + 6k
