x2 - 6x - 15 can be factored as (x - 7.899)(x + 1.899) The number values are actually 3 ± 2√6 so the 'accurate' factors are ( x - [3 + 2√6])(x - [3 - 2√6])
To solve 6x - 7 = 35, first you add 7: 6x - 7 + 7 = 35 + 7; i.e. 6x = 42. Then divide by 6: 6x/6 = 42/6, or x = 7.
6x - 5y = 15 6x - 6x - 5y = 15 - 6x -5y = -6x + 15 (-5y)/-5 = (-6x)/-5 + 15/-5 y = 6/5x - 3 where 6/5 is the slope and y-intercept is -3.

log (6x + 5) = 26x + 5 > 06x + 5 - 5 > 0 - 56x > - 56x/6 > -5/6x > -5/6log (6x + 5) = 210^2 = 6x + 5100 = 6x + 5100 - 5 = 6x + 5 - 595 = 6x95/6 = 6x/695/6 = xCheck:
6 is 6(x-1)
1, 2, 3, 6, x, 2x, 3x, and 6x.
6x-6y=6(x-y) The factors of 6(x-y) are 6 and (x-y).
x2 + 6x - 72 = (x + 12)(x - 6)
x2-6x can be factored into x(x-6). Simply factor out the "x" from both factors.
The question is not clear but this is how you would solve it.Numerical factors in this term have been multiplied.4 - 6 * 40x4 - 240xAnswer = -240x + 4Hope this help.
The greatest common factor of 12xy2 + 6x is 6x. The greatest common factor of 12 and 6 is 6, and the greatest common factor of xy2 and x is x. If you took 6x out of both factors, the end result would be 2y2+1
-6x = 6y + 6 -6x = 3y - 12 Subtracting the second from the first gives: -6x - -6x = 6y - 3y + 6 - -12 → 0 = 3y + 18 → 3y = -18 → y = -6 Substituting in the first: -6x = 6y + 6 → -6x = 6(-6) + 6 → -6x = -36 + 6 → -6x = -30 → x = 5 Thus x = 5, y = -3 solve the simultaneous equations.
To factorise this completely you need to be aware that 216 = 63. (x3 + 216) = (x + 6)(x2 - 6x + 36)
X2 - 6X + 27 = 0 what are the factors of 27 that add to - 6? None! This polynomial is unreal and does not intersect the X axis.
6x+13 = 97-6 6x = 97-6-13 6x = 78 x = 13
It simplifies to: -12-6x
