Question

$( {a}^{2} + 2b {)}^{2} productos \: notables$

​

Answer 1

Explicación paso a paso:

Productos notables: binomio al cuadrado

${(a + b)}^{2} = {a}^{2} + 2ab + {b}^{2}$

Entonces:

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

Resolvemos

${a}^{4} + 4 {a}^{2} b + 4 {b}^{2}$
