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
