x2 - x10 + x5 - x12 - x3

x2 - 4x - 32 = (x - 8)(x + 4)

x2 + 4x - 32 = (x + 8)*(x - 4)

x12 = (x6)2 = (x2)6 = x2x2x2x2x2x2

x2+4x-32 = (x-4)(x+8) when factored

x2 + 12x + 32 = (x + 8)(x + 4)

f(x) = x6 - 3x g(x) = x2 - 4 f(g(x)) = f(x2 - 4) = (x2 - 4)6 - 3(x2 - 4) = (x2 - 4)6 - 3x2 - 12 = (x12 - 24x10 + 240x8 - 1280x6 + 3840x4 - 6144x2 + 4096) - 3x2 - 12 = x12 - 24x10 + 240x8 - 1280x6 + 3840x4 - 6147x2 + 4084

x2 + 12x + 32 = (x + 4)(x + 8)

x2 + 12x + 32 = x2 + 8x + 4x + 32 = x*(x + 8) + 4*(x + 8) = (x + 8)*(x + 4)

64. because every letter is replaced with the number of the position in the alphaeth, and then doubled. A=1 x2= B=2 x2= D=4 x2= H=8 x2= P=16 x2= 16 x2= 32 x2= 64

-32

2x2=4 x2=8 x2=16 x2 = 32 and 5x5 = 25 so no, I guess not.

x2 - 8x + 32 = 0 (assuming)you can factor or use the quadratic equation.I recommend the quadratic equation.

no

x2 - 12x + 32 = 0 x2 - 8x - 4x +32 = 0 x(x -8) - 4(x -8) = 0 (x - 4)(x - 8) = 0 x = 4 or x = 8

if that's +32, it factors to -(x - 4)(x + 8)

y varies inversely as x2 so y = c/x2 for some constant c. When x = 5, y = 4 So c = x2y = 100 that is y = 100/x2 Then, when x = 2, y = 100/4 = 25

9 - x2 = 32 - x2 = (3 - x)(3 + x)

32*2*1 = 64 cubic feet.

it depends on what x2 and x are. so an example is 32 -3=3 cause 3 times 2 =6

When factored: (x+4)(x-8)

(x+8)(x-4)
