I think that wants to be 16x2 - 40xy + 25y2 That factors to (4x - 5y)(4x - 5y) or (4x - 5y)2
24x4 + 16x² - 8 = 8(3x4 + 2x² - 1) = 8(x² + 1)(3x² - 1).
The GCF is 8.
If that's -16x, that factors to (x - 8)(x - 8) or (x - 8)2
The GCF is 2x.
16 and x
2 * 2 * 2 * 2 * x * x * x = 16x^3
2 times 2 times 2 times 2 times x = 16x
In the absence of signs I have assumed the term in 16x and 60 are negative: ie x2 - 16x = -60 or x2 - 16x + 60 = 0 Factors of 60 which total -16 are -6 and -10, so (x - 6)(x - 10)
That factors to (x - 14)(x - 2)
16x + 2 - 8 = 16x + 24 implies 16x - 6 = 16x + 24 subtracting 16x from both sides, this implies: -6 = 24 So the equation has no soultions.
Too bad that's not x^2 - 16x + 64 which factors to (x - 8)(x - 8)
16x + 2 - 8 = 16x + 24 implies 16x - 6 = 16x + 24 subtracting 16x from both sides, this implies: -6 = 24 So the equation has no soultions.
16x-32 = -16
15x-16x = -1
sqrt[(16x)4] = (16x)2 = 256x2
There can be no such number. Since if x is such a number then 4x is a square number with more factors. and if 4x is the number then 16x has more, etc.
