Find: P%28-1%2F2%29 if:
P%28x%29+=+2x%5E4%2Bx%5E3%2B12 Simply replace the x's with -1%2F2 and evaluate.
P%28-1%2F2%29+=+2%28-1%2F2%29%5E4%2B%28-1%2F2%29%5E3%2B12
P%28-1%2F2%29+=+2%281%2F16%29%2B%28-1%2F8%29%2B12
P%28-1%2F2%29+=+2%2F16-1%2F8+%2B+12 Reduce 2%2F16+=+1%2F8
P%28-1%2F2%29+=+1%2F8-1%2F8%2B12 Simplify.
P%28-1%2F2%29+=+12
