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

The equation then becomes 2x=10 2x/2 = x and 10/2 =5

then x=5. does it work 5x5=10+3*5 YES

Since the y-variable is isolated in both equations, set the two right sides of the equations equal

x^2-7x+4=-8x^2+56x-86

Combine all like terms on one side of the equal sign

9x^2-63x+90=0. factor out the 9 to get** 9(x^2-7x+10)=0**

Now solve the equation**(x^2-7x+10)=0**. The solutions are x=5 and x=2

Calculate the y-value tof be y=-6

The two solutions are**(2,-6) and (5,-6)**

Graphically, here is how the two curves intersect. One intersection point in the screen capture is (2,-6). You can read that the other intersection point is (5,-6)

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

8x-9- (x plus 1)=8x-9-x-1=8x-x-9-1=7x-10

Solve for x

5x+3x+(-15) + 5 becomes 8x-10=180

move 10 from left to right and you get8x190

8x = 190

x = 23.75

so the first angle is (5*23.75)-15 = 103.75

and the second angle is (3*23.75) +5 = 76.25

check by adding 76.25+103.75 = 180

Make sense? I love math, let me know it you need more help

(4+x)(5-x)=(2+x)(7-x)

20-4x+5x-x^2=14-2x+7x-x^2

20+x=14+5x

20-14=4x

x=3/2:ans;

20-4x+5x-x^2=14-2x+7x-x^2

20+x=14+5x

20-14=4x

x=3/2:ans;

the exact equation is

15x^2 - 21x - 18

=3(5x^2 - 7x - 6)

=3{5x^2 -(10-3)x -6 }

=3{5x^2 - 10x + 3x -6}

=3{5x(x - 2) + 3(x-2)}

=3(x-2)(5x+3) these are the factors

Thanks
