Question

the product of (x/5-y/4) and 5x²-4y² is​

Answer 1

Answer:

The product of (x/5-y/4) and 5x²-4y² is​

= x²+y³-xy[500x+320y]/400

Step-by-step explanation:

(1/5x-1/4y)(5x²-4y²)

(x/5-y/4)(25x²/5-16y²/4)   -#here multiply and divide it by 5 and 4

[(4x-5y)/20][(100x²-80y²)/20]  #lcm making denominator equal

[(4x-5y)(100x²-80y²)]/400   #multiply both

(400x³-500x²y-320xy²+400y³)/400

x²+y³-xy[500x+320y]/400
