Multiply.......... ( {a}^(2) - 2ab + {b}^(2) ) \: by \: ( - {a}^(2) b) ​

Question

Multiply..........

`( {a}^(2) - 2ab + {b}^(2) ) \: by \: ( - {a}^(2) b)`
​

Answer 1

`\rm( {a}^(2) - 2ab + {b}^(2) ) \: by \: ( - {a}^(2) b)`

`\displaystyle \rm( {a}^(2) * - {a}^(2) b) - (2ab * - {a}^(2) b) + ( {b}^(2) * - {a}^(2) b)`

`\rm{ - {a}^(4) b} + {2a}^(3) {b}^(2) - {a}^(2) {b}^(3)`
