$x^{3} + 6 x^{2} - 7 x$ $x^3+6x^2-7x$

Explanation:

Each term in the bracket is $multiplied$ $color(blue)"multiplied"$ by x. This is called the $distributive law .$ $color(blue)"distributive law".$

$\Rightarrow x (x^{2} + 6 x - 7)$ $rArrcolor(red)(x)(x^2+6x-7)$

$= (x \times x^{2}) + (x \times 6 x) - (x \times 7)$ $=(color(red)(x)xx x^2)+(color(red)(x)xx6x)-(color(red)(x)xx7)$

$= x^{3} + 6 x^{2} - 7 x$ $=x^3+6x^2-7x$
