10x2 - 64 = 36x + 6x2
Subtract 6x2 from both sides:
4x2 - 64 = 36x
Subtract 36x from both sides:
4x2 - 36x - 64 = 0
Divide everything by 4:
x2 - 9x - 16 = 0
Use the quadratic formula:
x = (9±√(92-4(-16)))/(2)
x = (9-√(145))/2 or x = (9+√(145))/2
x + 36 = 82x = 82 - 36x = 46
The expression is likely 4x2 - 36x +81 which is the same as (2x - 9)(2x - 9) or (2x - 9)2
sqrt(x + 2) = 6x + 2 = 36x = 34whew !
3x2 + 36x + 81 = 3(x2 + 13x + 27)
32 - 121 - 64 = 36x => -153 = 36x so that x = -4.25
52x - 7 = 33 - 36x + 4 52x + 36x = 33 + 7 + 4 88x = 44 x = 1/2
x + 36 = 82x = 82 - 36x = 46
The expression is likely 4x2 - 36x +81 which is the same as (2x - 9)(2x - 9) or (2x - 9)2
16 + x = 36x = 36 - 16 = 2016 + 20 = 36
sqrt(x + 2) = 6x + 2 = 36x = 34whew !
3x2 + 36x + 81 = 3(x2 + 13x + 27)
32 - 121 - 64 = 36x => -153 = 36x so that x = -4.25
36x-9y = 15 -9y = -36x+15 y = 4x-5/3 in slope intercept form
-3x + 6 = -30 -3x = -30 - 63x = 36x = 36/3Therefore, x = 12.
x=-12
