Question

Find each of the following products: (2/5x-1/2y)(10x-8y)​

Answer 1

Answer:

=(2/5x*10x)(-1/2y*-8y)

=4x²*4y²

=16x²y²

Answer 2

$\huge\underline\mathsf{Answer}$

➠$\tt(25x−12y)(10x−8y)$

➠$\tt=(25x+−12y)(10x+−8y)$

$\tt➠(25x)(10x)+(25x)(−8y)+(−12y)(10x)+(−12y)(−8y)$

➠$\tt=250x^2−200xy−120xy+96y^2$

➠$\tt=250x^2−320xy+96y^2$
