Factor. Look for a GCF first. X^3+2x^2-48x

Answer:

x(x - 6)(x + 8)

Step-by-step explanation:

First, the GCF of these 3 terms is x.

So to separate x from this it now becomes x(x^2 + 2x - 48).

Now to factor the expression inside the parentheses easily I use "a" and "b" to make it easier.

a + b = 2 (from 2x)

a * b = -48 (from third term of expression)

a = -6, b = 8

Substitute "a" and "b" and I get: x(x - 6)(x + 8)

If D is the midpoint of CE, CD= 9x-7, and DE= 3x+17, find CE
tatuchka [14]
Hello!

Since D is the midpoint and the two equations are and both sides of point D the equations equal each other

9x - 7 = 3x + 17

Now you solve it algebraically

Add 7 to both sides

9x = 3x + 24

Subtract 3x from both sides

6x = 24

Divide both sides by 6

x = 4

Now we put this into both equations and add them

9(4) - 7 = 29
3(4) + 17 = 29

29 + 29 = 58

The answer is 58 units

Hope this helps!
