You have to use the

**F**irst

**O**utside

**I**nside

**L**ast

method.

5a*5a = 25a^{2 }---**F**irst

5a*5 = 25a ---**O**utside

5*5a = 25a ---**I**nside

5*5 = 25 ---**L**ast

And now you add all these up for your answer.

25a^{2 }+25a + 25a+ 25

**25a ^{2} + 50a + 25**

And there you go, that's your answer.

So we wil solve this like;

$$(5a+5)(5a+5)$$

$$=5a(5a+5)+5(5a+5)$$ (now we will multiply them)

$$=25a^2+25a+25a+25$$ (now we will add the like values)

$$=25a^2+50a+25$$ $$ANSWER$$

i hope uve understood by now but if not then pls be freee to ask!

Hope this helps!
