Simplify the polynomial expressions by combining like terms, and then multiply the resulting binomial expressions to find their product. (8x − 9 − 2x)(15 + 5x − 5)

For this case we have the following expression:
 
 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:
 
 Then, doing distributive property we have:
 
 Adding similar terms:
 
 
 The simplified expression is:
 

I’m pretty sure the answer is counter steer.
