Question

(5x - 3y)³
plsss answee​

Answer 1

Step-by-step explanation:

(5x-3y)^3

this is in the form of

(a-b)^3b= a^3-3a^2b-3ab^2+b^3

=(5x)^3 - 3.(5x)^2.3y - 3.5x.(3y)^2 - (3y)^3

= 125x^3 - 3.25.x^2.3y - 3.5x.9y^2 - 27y^3

= 125x^3 - 225x^2 - 135y^2 - 27y^3

hope this helps you

Answer 2

Answer:

$(a - b)^{3} = a {3} - b^{3} - 3ab7(a - b)$

hence

$(5x - 3y)^{3} = 125 {x}^{3} - 9 {y}^{3} - 15x - 9y(5x - 3y)$

$(5x - 3y)^{3} = 125 {x}^{3} - 9 {y}^{3} - 75x ^{2} - 27y ^{2}$
