For this case we have the following expression:
[tex](8x - 9 - 2x) (15 + 5x - 5)
[/tex]
The first thing we must do is to rewrite the expression as the product of two binomials.
To do this, we add similar terms.
We have then:
[tex](6x - 9) (5x + 10)
[/tex]
Then, doing distributive property we have:
[tex]30x ^ 2 + 60x - 45x - 90
[/tex]
Adding similar terms:
[tex]30x ^ 2 + 15x - 90[/tex]
Answer:
The simplified expression is:
[tex]30x ^ 2 + 15x - 90[/tex]
