Answer:
1989xsquared y + 585xsquared+ 2618xy + 770x - 8075y - 2375
Step-by-step explanation:
(9x + 25) x (13x - 19) x (17y + 5)
(117x squared - 171x + 325x - 475) x (17y + 5)
(117x squared + 154x - 475) x (17y + 5)
[tex](9x + 25) (13x - 19) (17y + 5)=1989x^2y + 585x^2+ 2618xy + 770x - 8075y - 2375[/tex]
We have to simplify the expression:
(9x + 25)(13x - 19)(17y + 5)
Multiply the first two expressions as
[tex][9x(13x - 19)+25(13x - 19)](17y + 5)[/tex]
[tex]=(117x^2 - 171x + 325x - 475)(17y + 5)[/tex]
[tex]=(117x^2 + 154x - 475)(17y + 5)[/tex]
[tex]=17y(117x^2 + 154x - 475) + 5(117x^2 + 154x - 475)\\=1989x^2y + 585x^2+ 2618xy + 770x - 8075y - 2375[/tex]
Therefore after simplifying , we get
[tex](9x + 25) (13x - 19) (17y + 5)=1989x^2y + 585x^2+ 2618xy + 770x - 8075y - 2375[/tex]
