Your question is interpreted in following way as it is not clear as cube of what & minus of what?
2x minus x cube plus 5 x minus 2

Solution 1:
= 2 x -1 x cube plus 5 x minus 2
= -2x cube plus 5 x minus 2
= cube of -2 plus 5 x minus 2
= (-8 +5) x -2
= -3 x -2
= 6

Solution2:
=2x-1x cube of +5 x -2
= -2 x 125 x -2
= 500

I think logically the solution 2 must be right. How you interpret the question is important.

### Im trying to solve the equation 5x=10-3x

5x (-3x) = 2x -3x - -3x = 0
The equation then becomes 2x=10 2x/2 = x and 10/2 =5
then x=5. does it work 5x5=10+3*5 YES

### What is rational expression of (22x +11) (10x2 +5x)

I assume the 10x2 means 10 squared. (I will show it as 10x**2)
(22x+11)(10x**2+5x) factors into"
11(2x+1)*5(2x**2+1x)
=55(2x+1)(2x**2+1x)
=(55x)(2x+1)(2x+1)
Multiplied out, it becomes 55x(4x**2+4x+1)
= 220x**3 + 220x**2 + 55x

### Find two numbers such that the sum of the first and three times the second is 5 and the sum of the second and 2 times the first is 8

Let the two numbers be X and Y:
X + 3Y = 5
2X + Y = 8

Rewrite the second equation to Y = 8 - 2X and substitute in first equation:
X + 3(8-2X) = 5
X + 24 - 6X = 5
-5X + 24 = 5
-5X = 5 - 24
-5X = -19
X = 19/5 = 3.8
Y = 8 - 2(3.8) = 8 - 7.6 = 0.4

Check: 3.8 + 3(0.4) = 3.8 + 1.2 = 5
2(3.8) + .4 = 7.6 + 0.4 = 8

### Give the polynomial function whose roots are -2 1 and 3

We can write this polynomial as:
• (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
x^3-2x^2-5x+6 is polynomial with roots -2, 1, 3.

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).

### How to graph y=-5/2x-2 on ti-84 plus calculator

Press Y= (the key at the very top left, above the blue 2ND key). On the Y1= line, enter (-) 5 / ( 2 X ) - 2 if the function is "negative five over 2x minus 2" or (-) 5 / 2 X - 2 if the function is "negative five-halves x minus 2".
(The (-) is the key to the right of the decimal point.) Then press GRAPH (the very top right key) and the graph should appear. You can press WINDOW (just to the right of the Y=) and change the window settings if you wish.

### How do I solve x and y in the following equations? 5x+3y=6 2x-4y=5 Thank you

You can solve it with following method.

5x+3y=6 2x-4y=5
So 5x=6-3y so 2[(6-3y)/5]-4y=5
So x=(6-3y)/5 so 12-6y-20y=25
so -26y=25-12
so -26y=13
so y= -(1/2)
2x-4y=5
so 2x=5+4y
so 2x=5+4(-1/2)
so 2x=(10-4)/2
so 2x=6/4
so x =3/2

The value of x=3/2 and value of y= -1/2

Let me know if you need further assistance.
Thanks for using FixYa.

### How do i solve this problem 3x+25=5x using my TI 84 plus

i think there are programs but with something as simple as that you should be able to work it out manually....
3x+25-5x=5x-5x
-2x+25-25=0-25
-2x=-25
x=25/2 or 12.5
