Question

(3x-5y)^3 expand by using identities

Answer 1

Step-by-step explanation:

(3x)³-3(3x)²(5y)-3(3x)(5y)²-(5y)³

27x³-135x²y-135xy²-125y³ is ur answer

${(3x-5y)}^{3}$

${(3x)}^{3} + {(-5y)}^{3} + 3(3x)(-5y)(3x -5y)$

${27x}^{3} - {125y}^{3} - 45xy(3x - 5y)$

${27x}^{3} - {125y}^{3} - {135x}^{2} y + {225xy}^{2}$
