6-3x = 5x-10x+2 4 = 8x-10x 4 = -2x x = -2
30 + 5x = 15 + 10x 30 = 15 + 5x 15 = 5x x = 3
(2x+3)/(10x2+21x+9)Factor the quadratic expression in the denominator:(2x+3)/(5x+3)(2x+3)which becomes:1/(5x+3) or (5x+3)-1
3x - 7 = 5x + 133x - 5x = 13 + 7-2x = 20x = -10x=-3
10x+7 = 5x+32 10x-5x = 32-7 5x = 25 x = 5
If you mean: (2x+2)(5x-5) then it is equivalent to 10x^2 -10
5x * 2x = 10x^2
6-3x = 5x-10x+2 4 = 8x-10x 4 = -2x x = -2
10x - 5x + 5x = 10x
20x2 + 22xy + 6y2 = 20x2 + 10xy + 12xy + 6y2 = 10x(2x + y) + 6y(2x + y) = (2x + y)(10x + 6y) = 2(2x + y)(5x + 3y)
30 + 5x = 15 + 10x 30 = 15 + 5x 15 = 5x x = 3
-10x + 5x = -5x
10x - 78 = 1, 10x = 79, x = 7.9

6-3x = 5x-10x+10 6-3x = -5x+10 -3x+5x = 10-6 2x = 4 x = 2
-2(5x+3)-2x<-3(2x-4)+2
It is: 10x^2 -4x = 2x(5x-2)
