Explicación paso a paso:

$x^2+7x+10x^2+x-12x^2+5x+6\cdot \:6z^2+11z+4\cdot \:6x^2-7x-3\\\\=x^2+10x^2-12x^2+4\cdot \:6x^2+7x+x+5x-7x+6\cdot \:6z^2+11z-3\\\\=-x^2+4\cdot \:6x^2+7x+x+5x-7x+6\cdot \:6z^2+11z-3\\\\=-x^2+4\cdot \:6x^2+6x+6\cdot \:6z^2+11z-3\\\\=-x^2+24x^2+6x+6\cdot \:6z^2+11z-3\\\\=-x^2+24x^2+6x+36z^2+11z-3\\\\=23x^2+6x+36z^2+11z-3$
