Formula

Expand the expression

Answer

$\left( u-4 \right) \left( u+7 \right)$

$u ^ { 2 } + 3 u - 28$

Organize polynomials

$\left ( \color{#FF6800}{ u } \color{#FF6800}{ - } \color{#FF6800}{ 4 } \right ) \left ( \color{#FF6800}{ u } \color{#FF6800}{ + } \color{#FF6800}{ 7 } \right )$

$ $ Organize the expression with the distributive law $ $

$\color{#FF6800}{ u } ^ { \color{#FF6800}{ 2 } } \color{#FF6800}{ + } \color{#FF6800}{ 3 } \color{#FF6800}{ u } \color{#FF6800}{ - } \color{#FF6800}{ 28 }$
