One of the factors of the polynomial x3 + 5x2 + 6x is (x2 + 3x). What is the other factor?

butalik [34]

Answer:

x+2

Step-by-step explanation:

Dividing the poly by the known factor:

x3+5x2+6x | x2+3x

-x3-3x2 x + 2 <- the answer is here

2x2+6x

-2x2-6x

To prove that, let's multiply the two factors and find the pylonomial back on:

(x2+3x).(x+2) = x3 + 2x2 + 3x2 + 6x = x3 + 5x2 + 6x

Does anyone know how to do this

Thepotemich [5.8K]

Answer:

The solution is B

Step-by-step explanation:

$x + 5 \geqslant 1 \\ x \geqslant 1 - 5 \\ x \geqslant - 4$

then:

$x - 7 < - 3 \\ x < - 3 + 7 \\ x < 4$

therefore, interval [limits] of x:

$- 4 \leqslant x < 4$
