(x-7) to the power of 2= 64       What is x?

Some folks seem to have forgotten this is a quadratic, and they have two (2) roots!\n\n(x - 7)^2 = 64\n\nx - 7 = ± 8 (take the square root of both sides)\n\nso \n\nx = 7 + 8 = 15 \n\nor \n\nx = 7 - 8 = -1\n\nyou could expand this out and use the quadratic equation to solve it as well:\n\nx^2 - 14x + 49 = 64\n\nx^2 -14x - 15 = 0  a = 1 b = -14  c = -15\n\nthe rest is left to the student as an exercise. :^)

maybe something like 7^(1/3) over 7^(1/2)\n\nthat's the same as the cube root of 7 over the square root of 7.\nTo solve it, you would just subtract the exponents and you'd get 1 over 7^(1/6)\n\nI hope that is what you are looking for.

1 - 64x^2 = (1 + 8x)(1 - 8x)\n\ny^2 - 12y + 36 = (y - 6)(y - 6)  or (y - 6)^2

Take half of the coefficient of the x term, which comes to 7/2.\nSquare that, which comes to 49/4.\n(x + 7/2)^2 = x^2 +7x + 49/4

anything to the power of zero is one. so 1+1=2. Y=2. 2X2=4.

Since you're dividing two monomials with the same base (x), you subtract the exponents so the answer is x^6. \n\nHope this helps ;-)

we have \nx^2 -84x+1764=0\nit's equation of second degree\nsolution x=42

-60 + 20x = 24x +72\n-60 = 4x +72\n-132 = 4x\n-33 =x

(x-7)(x-7)\nuse the FOIL method (first outer inner last)\nx times x= x squared\nx times -7 =-7x\n-7 times x =-7x\n-7 times -7 = 49\nxsqured-14x+49\nthats factoring, but u cant really solve cuz u didnt put an equation...\n\nunderstand?

If you are sloving for X then anything greater than 2 will work. basically it is 6 time what (X) will be greater than 12. Well 6x2=12 so that won't work.

x^2 - 8x + 16\n\n\nthe person above me said it is -x^2 but that is incorrect because -x * -x = x^2

49^-1/2 = 1/(49^{1/2}) = 1/7 which is clearly very different from -7\n`

Let x = "one number". \nThen, the "another number" is 2x.\n\nWhen the larger number is decreased by 10,\n\n2x - 10\n\nThe result is 2 greater than the smaller number\n\nx + 2\n\nTherefore,\n\n2x - 10 = x + 2, and\nx = 12.\n\nSo the two numbers are x and 2x, or 12 and 24.\n\nLet's put it back into the problem.\n\nOne number is twice another.  24 is twice 12.\nWhen the larger number is decreased by 10 (24 - 10 = 14), the result is 2 greater than the smaller number (2+12 = 14).  Therefore that's the answer!\n\nHappy solving!
