Question

factorise 14x²y²-10x²y+8xy²
pls give the answer ASAP...​

Answer 1

27y³ + 125z³

We know that,

x³ + y³ = (x+y) ( x² - xy + y² )

So, here

x = 3y , y = 5z

= 27y³ + 125z³ = (3y + 5z) { (3y)² - 3y*5x + (5z)² }

= 27y³ + 125z³ = (3y + 5z) { 9y² - 15xy + 25z² }

(ii) 64m³ - 343n³

We know that,

x³ - y³ = (x-y) ( x² - xy + y² )

So, here

x = 4m , y = 7n

= 64m³ - 343n³ = (4m - 7n) { (4m)² + 4m*7n + (7n)² }

= 64m³ - 343n³ = (4m - 7n)

Answer 2

Answer:

2xy(7xy-5x+4y)

Step-by-step explanation:

14 x^2 -10x^2y+8xy^2

=2xy(7xy-5x+4y)
