Verified answer

(9a + a2 + 14) (10a + a2 + 25)

___________________________

12a+a2+35

First of all, if this equation is equal with o (zero), we have:

A2+ 12a+35=0

And

A2+10a+25=0

From here results:

A2=25

A=-5

I hope this can help you!

Cheers!

= (a^2 + 5a + 5a + 25) ÷ [(a^2 + 7a + 5a + 35)/(a^2 + 7a + 2a + 14)]

= [(a + 5)(a + 5)] ÷ [(a + 5)(a + 7)/(a + 2)(a + 7)]

= [(a + 5)^2] ÷ [(a + 5)/(a + 2)]

= (a + 5)(a + 2)

= a^2 + 2a + 5a + 10

= a^2 + 7a + 10
