// splitTheMiddle [algebra]
// splitTheMiddle
decompose Bx into (b₁)x and (b₂)x such that b₁·b₂ = A·C and b₁ + b₂ = B.
// SYSTEM_RULES:
* find the two middle x-terms that multiply to A·C and add to B, from 12 candidates or by typing them.
* wrong selection triggers a 2.0s system lockout and -3 pts.
* each correct term scores 2 pts and finishing a pair adds 4, both times the difficulty multiplier. penalties are not scaled.
// difficulty
no tiles to hint at the answer. type both terms, like -27x and 8x, in either order. scores on its own leaderboard.
