SOLVE THIS​

Answer 1

Answer:

${(a + b})^{3} = ({a + b})^{2} (a + b) \\ \\ = >( {a }^{2} + {b}^{2} + 2ab)(a + b) \\ \\ \\ = > {a}^{3} + {a}^{2} b + {b}^{2} a + {b}^{3} + 2 {a}^{2} b + 2a {b}^{2} \\ \\ \\ = > {a}^{3} + {b}^{3} + 3 {a}^{2} b + 3 {b}^{2} a$

$\huge\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\pink{R}}}}$

(a+b)³=(a+b)(a+b)(a+b)___multiply (a+b) and (a+b)

Now

(a+b)³=(a²+ab+ab+b²) (a+b)

(a+b)³=(a²+2ab+b²) (a+b)

(a+b)³=a³+a²b+2a²b+2ab²+ab²+b³____combine like terms

Now

(a+b)³=a³+3a²b+3ab²+b³

Or

(a+b)³=a³+b³+3ab(a+b)
