Given:The given algebraic expression is $36a^2+36a+9$.To do:We have to factorize the expression $36a^2+36a+9$.Solution:Factorizing algebraic expressions:Factorizing an algebraic expression means writing the expression as a product of two or more factors. Factorization is the reverse of distribution. An algebraic expression is factored completely when it is written as a product of prime factors.$36a^2+36a+9$ can be written as, $36a^2+36a+9=(6a)^2+2(6a)(3)+(3)^2$             [Since $36a^2=(6a)^2, 9=(3)^2$ and $36a=2(6a)(3)$]Here, we can observe that the given expression is of the form $m^2+2mn+n^2$. So, by using the formula $(m+n)^2=m^2+2mn+n^2$, we can factorize the given expression.Here, $m=6a$ and $n=3$ Therefore, $36a^2+36a+9=(6a)^2+2(6a)(3)+(3)^2$$36a^2+36a+9=(6a+3)^2$$36a^2+36a+9=(6a+3)(6a+3)$Hence, the given expression can be factorized as ...
