2x+1 = 9 2x = 9-1 2x = 8 x = 4
9(2x - 1)(2x + 1)
6x - 9 + 2x + 1 = 8x -8
If you mean: -3x-5x+1+8x-2x-9 then the result is -2x-8
2x-6y = 9 Rearranging: 6y = 2x - 9 Divide through by 6: y = (1/3)x - 3/2
2x+1 = 9 2x = 9-1 2x = 8 x = 4
2x + 1 = 9 2x = 9 - 1 2x = 8 2x/2 = 8/2 x=4
3x+9=2x+10 3x+9-2x=10 9+x=10 x=1
9(2x - 1)(2x + 1)
2x + 9 = 6x + 1 9 - 1 = 6x - 2x 8 = 4x x = 2
y = -1/(3x7 + 2x - 9)y = -(3x7 + 2x - 9)-1y' = -(-1)(3x7 + 2x - 9)-2(3x7 + 2x - 9)'y' = (3x7 + 2x - 9)-2(21x6 + 2)y' = (21x6 + 2)/(3x7 + 2x - 9)2
2x2 + 17x - 9 = 2x2 + 18x - x - 9 = 2x(x + 9) - 1(x + 9) = (2x - 1)(x + 9)
9-2x=-1 subtract the 9 from both sides -2x=-10 divide each side by -2 x=5
3x2 + 2x + 2 = 0 Can not be factored. You can however solve it for x: 3x2 + 2x = -2 x2 + 2x/3 = -2/3 x2 + 2x/3 + 1/9 = -2/3 + 1/9 (x + 1/9)2 = -5/9 x + 1/9 = ±√(-5/9) x = -1/9 ± i√(5/9) x = -1/9 ± i√5 / 3 x = -1/9 ± 3i√5 / 9 x = (-1 ± 3i√5) / 9
6x - 9 + 2x + 1 = 8x -8
(x - 1)(2x - 9)
If you mean: -3x-5x+1+8x-2x-9 then the result is -2x-8
