9+6x = 25-2x 6x+2x = 25-9 8x = 16 x = 2
(6x+5)(6x-5)
If you mean: 6x = 25+x then x = 5
x2 - 6x = 16 ∴ x2 - 6x + 9 = 25 ∴ (x - 3)2 = 25 ∴ x - 3 = 25 ∴ x = 28
5x+15 = 6x-10 5x-6x = -10-15 -x = -25 x = 25
(6x + 5)(6x - 5)
362+60x+25 (6x+5)(6x+5)
If: 9x+7 = 6x+25 Then: x = 6
(6x + 5)(6x + 5) or (6x + 5)2
2x2 - 6x - 25 = 0. Solutions are 5.34 and -2.34
it's (25 - 6x)
Given 6x-1 = 29: 6x = 30 x = 5 Therefore x² = 25, adding 25 and 5 gives you 30
