If B=1-q and c=3q-q^2-1 find an expression that equals b-c in standard form

idk bring the function back   im not smart

step-by-step explanation:

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
