Question

( + y+ z)^3 Elaborate the given algebraic expression. Thanks . ​

Answer 1

Answer:

(y + z)^3, when Elaborated, gives an Expansion of y^3 + z^3 + 3y^2z + 3yz^2

Step-by-step explanation:

$using \: the \: identity \: (x + y) {}^{3} = {x}^{3} + {y}^{3} + 3xy(x + y) \\ {(y + z)}^{3} = {y}^{3} + {z}^{3} + 3(y)(z)(y + z) \\ using \: the \: distributive \: law \\ = > (y + z) {}^{3} = {y}^{3} + {z}^{3} + 3 {y}^{2} z + 3y {z}^{2}$
