x2 + 8x2 = 9x2
x2 - 11x + 24 = (x - 3)(x - 8)
x2 - (2x)2 = x2 - 4x2 = -3x2 x2 - 2x2 = -x2
That depends on what you're doing to the 8. It's either 4(x2 + 2) or 4(x2 - 2)
(X2) (X2) = X4 x squared multiplied by x squared is x raised to the 4th power.
x2 - 9x + 8 = (x-1)(x-8)
x2 + x2 = 2x2 2x^2
X2+y2=25 (x-8)2+y2 =41
64-x2 = (8-x)(8+x) when factored
x^3 - 121x
(x2)2 = x4
(x2 + 14 + 48 / (x + 8) = (x2 + 62) / (x + 8) =(x2 + 8x - 8x - 64 + 126) / (x + 8) = x - 1 + 126/(x+8)
4x2 - x2 = 3x2
Since it's x2*x2, you would add the exponents giving you x4
x2 + 6x + 8 =(x + 2)(x +4)
Square root of 61. Distance formula is: square root of ((x1-x2)squared + (y2-y1)squared))
x2-x-56 = (x+7)(x-8) when factored
2x2 + x2 = 3x2
7x2*x2 = 7x4
Assuming you mean x squared plus 5x squared... the answer is 6x squared.
X2 A number to the second power is squared.
