[input]plot( abs( -2x-1 ), 7, x=-4..4 )[/input]

solve: -2x-1 = 7 and -(-2x-1) = 7

-2x-1 = 7
-2x-1+1 = 7+1
-2x = 8
-2x/-2 = 8/-2
x = -4

-(-2x-1) = 7
2x+1 = 7
2x+1-1 = 7-1
2x = 6
x = 6/2
x = 3

[input](3x + 1)(3x - 1) = 15[/input]

(3x + 1)(3x - 1) =
3x*3x+1*3x+3x*-1+-1 =
9x^2-1

somit:
9x^2-1 = 15
9x^2-1+1 = 15+1
9x^2 = 16
9x^2/9 = 16/9
x^2 = 16/9
wuzel( x^2 ) = wurzel( 16/9 )
wuzel( x^2 ) = wurzel( 16)/ wurzel(9 )
x = +4/3 und -4/3
