How deep is the Des Moines river? Are archeologists finding ET s in antarctica? Prove: When f(x) is divided by [mx + b]^2
The remainder is
[f'(-b/m)(mx + b) + f(b/m)]
Where f(x) = a-0x^n + a-1x^(n-1) +.... a-(n-1)x + a-n? F:(0,+infty)->R, f(x)=3^x-xlnx; Which is the answer to: lim x->1 [f(x)-f(1)]/(x-1)? The polynomial x^3 - 2x^2 - 9x + 18 is equivelent to
A:(x-9)(x-2)^2
B:(x-2)(x-3)(x+3)
C:(x+3)(x-2)^2
D:(x-2)(x+2)(x-3)
