#color(red)(0.42)#

#-2(0.14)(-3)(0.5)#

#color(white)("XXX")=2xx(0.14)xx(3)xx(0.5)color(white)("xxx")#multiplying 2 negatives gives a positive

#color(white)("XXX")=(0.14)xx(3)xx(2)xx(0.5)color(white)("xxx")#rearrange to simplify

#color(white)("XXX")=(0.14)xx(3)color(white)("xxxxxxxxxxxxxx"#since #2xx0.5=1#

#color(white)("XXX")=0.42#
