(x + a)(x + b) =  {x}^{2} + (a + b)x + (a \times b) \\

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

{v}^{2} + ( - 7s {u}^{2} + s {u}^{2})v +( ( - 7s {u}^{2})(s {u}^{2} )) =  \\

{v}^{2}  - 6s {u}^{2} v - 7 {s}^{2} {u}^{4}   \\

Answer:

v² - 6su²v - 7s²u^{4}

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor, that is

= v(v + su²) - 7su²(v + su²) ← distribute both parenthesis

= v² + su²v - 7su²v - 7s²u^{4} ← collect like terms

= v² - 6su²v - 7s²u^{4}
