Maclaurin's Expansion
Expand f(x) = e x2-x up to the third non-zero term.
I keep getting 1 - x + (3/2)x2 +..., but the book gives the answer as 1 + x - (1/2)x2 +...
What am I doing wrong?

Look like the book used e^(x-x^2)??
Yeah, that's probably it. Thanks.

Is McLaurin's in FP2 on your exam board, just to go off at a tangent for a moment? Our entire Pure course seems to be in FP2 with CCEA.
Edexcel, no it's in FP3.
