Explanation:
#" find p(c) by substituting x = c into p(x)"#
#rArrp(c)=6c^4-c^2+2#
#"find " p(-2/3)" by substituting " c=-2/3" into p(c)"#
#rArrp(color(red)(-2/3))=6(color(red)(-2/3))^4-(color(red)(-2/3))^2+2#
#color(white)(xxxxxxxx)=6xx16/81-4/9+2#
#color(white)(xxxxxxxx)=96/81-36/81+162/81#
#color(white)(xxxxxxxx)=222/81=74/27#
