Question

(a+b) 3 =? complete formula​

Answer 1

Answer:

The formula is (a-b)³=a³-3a²b+3ab²-b³. You convert it to (a-b)³=a³-3ab(a-b)-b³ for an illustration. ... You take the drawing of the formula (a+b)³=a³+3a²b+3ab²+b³ from above and replace a by the difference a-b.

Answer 2

Answer:

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

OR

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

here is your answer.

hope it helps you..!!!
