2x + 7y - 14 = 0

One equation in 2 unknowns has many solutions. Generally you can just substitute x = 1,2,3,4,5 etc and find y. Let us stick to simple outcomes

7y = 14 - 2x

x = 7 y = 0

x = -7 y = 4

x = 14 y = -2

x = -14 y = 6

Please the reformulate the problem(?) with more care. Capital P is a different entity than p. Are you trying to factor out the polynomial (an algebra problem where the **Greatest** Common Factors have no meaning), or are you trying to find the GCF of certain positive integers (an arithmetic problem)?

There are an infinite number of polynomials with those roots. Assuming you want one with the lowest degree, here are two:

x^3 - 2x^2 - 5x + 6

2x^3 - 4x^2 - 10x + 12

Since the roots of the polynomials are -2, 1, and 3, the values (x+2), (x-1), and (x-3) must be zero.

To get these polynomials, simply multiply

k * (x+2) * (x-1) * (x-3)

where k is any nonzero value.

x^3 - 2x^2 - 5x + 6

2x^3 - 4x^2 - 10x + 12

Since the roots of the polynomials are -2, 1, and 3, the values (x+2), (x-1), and (x-3) must be zero.

To get these polynomials, simply multiply

k * (x+2) * (x-1) * (x-3)

where k is any nonzero value.

We can write this polynomial as:

You can see this polynomial in following picture:

Notice that it intersects x axis for x=-2, 1 and 3 (because these are roots of polynomial).

- (x-(-2))*(x-1)*(x-3)=
- (x+2)(x-1)(x-3)=
- (x+2)[x*(x-3)-1*(x-3)]=
- (x+2)*(x^2-3x-x+3)=
- (x+2)(x^2-4x+3)=
- x*(x^2-4x+3)+2*(x^2-4x+3)=
- x^3-4x^2+3x+2x^2-8x+6=
- x^3-2x^2-5x+6

Note that (x^2 - 3x + 2) can be factored: (x-2)*(x-1)

First, divide by (x-1).

Second, divide by (x-2).

First, divide by (x-1).

Second, divide by (x-2).

Ok so first you need to find what x equals in terms of y. so use the first equation .2x+.7y=1.5 solve for x by the following steps

subract .7y from both sides: .2x= 1.5-.7y --->

divide by .2 on both sides: x= 7.5 - 3.5y. --->

Now plug in x= 7.5 - 3.5y for x in the second equation 0.3 (7.5 - 3.5y) -0.2y=1 --->

Distribute the .3: 2.25 - 1.05y -.2y = 1--->

solve for y by combining like terms (the y's) and subtractive 2.25: -1.25y = -1.25--->

divide by -1.25 and you get y= 1

Now go back to your x= 7.5 - 3.5y you solved for. Plug in 1 for y in the equation and solve for x--->

x=7.5-3.5(1) so x= 4 and y=1 yay your done!

subract .7y from both sides: .2x= 1.5-.7y --->

divide by .2 on both sides: x= 7.5 - 3.5y. --->

Now plug in x= 7.5 - 3.5y for x in the second equation 0.3 (7.5 - 3.5y) -0.2y=1 --->

Distribute the .3: 2.25 - 1.05y -.2y = 1--->

solve for y by combining like terms (the y's) and subtractive 2.25: -1.25y = -1.25--->

divide by -1.25 and you get y= 1

Now go back to your x= 7.5 - 3.5y you solved for. Plug in 1 for y in the equation and solve for x--->

x=7.5-3.5(1) so x= 4 and y=1 yay your done!

One way is to use the Polynomial Root Finder and Simultaneous Equation Solver app.

Press the APPS key, then select PlySmlt2 and press ENTER. Press ENTER to get past the opening screen, then select "POLY ROOT FINDER" and press ENTER. Select the order of the polynomial and other settings as desired. Press F5 (the GRAPH key) to go to the next screen. Enter the polynomial coefficients, then press F5 to solve. The next screen will show you the roots (unless you selected real roots and the polynomial doesn't have any real roots).

If you don't have the app installed, you can download it from

(5x+7)/(x^2+3x+2)

is the simplified answer because you can't break up the polynomials. The polynomials are like groups and you can't break them apart unless the polynomial itself can be simplified like

2x+4

can be simplified to 2(x+2)

so in which case you could simplify the problem down further.
