Question

(a^2-b) ^3=_____
please help guys send the correct answer ​

Answer 1

Answer:

$a^6 - b^3 - 3a^4b + 3a^2b^2$

Step-by-step explanation:

$(a^{2}-b)^{3}\\By formula \\(x+y)^{3} = x^3 + y^3 + 3xy(x+y)\\Therefore,\\(a^2 - b)^3 = (a^{2})^{3} + (-b)^{3} + 3(a^2)(-b)(a^2 -b)\\(a^2 - b)^3 = a^6 - b^3 -3a^2b(a^2-b)\\(a^2 - b)^3 = a^6 - b^3 - 3a^4b + 3a^2b^2$

Answer 2

Answer:

a⁶ - b³ - 3a⁴b + 3a²b²

Step-by-step explanation:

( a² - b )³

= ( a² )³ - b³ - 3a²b ( a² - b )

= a⁶ - b³ - 3a⁴b + 3a²b²
