$(-3/10a^2b^2c^2)xx(-4/3a^2b^2+9/2a^2b^2-1/4a^2b^2)$

$(-3/10xx-4/3)a^4b^4c^2+(-3/10xx9/2)a^4b^4c^2+(-1/4xx-3/10)a^4b^4c^2$

$+12/30a^4b^4c^2-27/20a^4b^4c^2+3/40a^4b^4c^2$

$+2/5a^4b^4c^2-27/20a^4b^4c^2+3/40a^4b^4c^2$

$(+2/5-27/20+3/40)a^4b^4c^2$

$(+16-54+3)/40a^4b^4c^2$

$(19-54)/40a^4b^4c^2$

$-35/40a^4b^4c^2$
