Hey :)
First, find the GCF.
It is 6 since it divides evenly into 42x and -18.

Second, factor out the gcf and divide each term by the GCF.
6(42x/6 - 18/6)

Lastly simplify.
6(7x-3)

There are many different ways to do it and that's one of them.


Hope this helps !!
Good luck:)

What is the value of x in the following equation? -3x-2=2x+8
Arlecino [84]

Answer:

-2 =x

Step-by-step explanation:

-3x-2=2x+8

Add 3x to each side

-3x+3x-2=2x+3x+8

-2 = 5x+8

Subtract 8 from each side

-2-8 = 5x+8-8

-10 = 5x

Divide by 5

-10/5 = 5x/5

-2 =x

What is the value of a and b F(x)=x(x+a)(x-b)
nalin [4]
Unfortunately, Tashara, you have not provided enuf info from which to calculate the values of a and b.  If you were to set  <span>F(x)=x(x+a)(x-b)  = to 0, then:

x=0,
x=-a
x=-b

but this doesn't answer your question.
Double check that you have shared all aspects of this question.</span>
