			$x^{2}$	$-$	$7x$	$+$	$12$
$x$	$-$	$1$	$x^{3}$	$-$	$8x^{2}$	$+$	$19x$	$-$	$12$
			$x^{3}$	$-$	$x^{2}$					During Subtraction $+x^{3}$ becomes $-x^{3}$, $-x^{2}$ becomes $+x^{2}$
				$-$	$7x^{2}$	$+$	$19x$	$-$	$12$
				$-$	$7x^{2}$	$+$	$7x$			During Subtraction $-7x^{2}$ becomes $+7x^{2}$, $+7x$ becomes $-7x$
							$12x$	$-$	$12$
							$12x$	$-$	$12$	During Subtraction $+12x$ becomes $-12x$ , $-12$ becomes $+12$
