Question

factorise 125x^3+64y^3​

Answer 1

Answer:

$= {125x}^{3} + {64y}^{3} \\ = {(5x)}^{3} + {(4y)}^{3} \\ = (5x + 4y)(25 {x}^{2} - 20xy +16 {y}^{2})$

Answer 2

$\huge\red{\mid{\fbox{\tt{Answer}}\mid}}$

$125x^3 + 64y^3\\(5x)^3 + (4y)^3\\now \ use \ the \ identity \ x^3+y^3 = (x+y) \ (x^2+xy+y^2) \\(5x+4y) \ [(5x)^2+5x \times 4y + (4y)^2]\\(5x+4y) \ (25x^2 + 5x \times 4y + 16y^2)$
