Enter the values for the highlighted variables that show how to subtract the rational expressions correctly:
startfraction 2 over x squared minus 36 endfraction minus startfraction 1 over x squared + 6 x endfraction = startfraction 2 over (x + 6) (x minus 6) endfraction minus startfraction 1 over x (x + a) endfraction. = startfraction b x over (x + 6) (x minus 6) x endfraction minus startfraction x minus c over (x + 6) (x minus 6) x endfraction. = startfraction d x minus x + e over (x + 6) (x minus 6) x endfraction. = startfraction x + f over (x + 6) (x minus 6) x endfraction. = startfraction g over x (x minus 6) endfraction
