Question

factorize: a2 +18a+72​

Answer 1

Hi mate!!

Hope u r good !!

Here is ur answer -

★ Factorizing using splitting the middle terms.

→Here, middle term is 18a

→And last term is  72

→We just have to find 2 nos. whose product is 72 and sum is 18

→ Thus, factorizing $a^{2} +18a+72$ we get -

$a^{2} +18a+72\\\\a^{2} +12a+6a+72\\\\a(a+12) 6(a+12)\\\\(a+12) (a+6)$

∴ factors of  $a^{2} +18a+72$ are  $(a+12)$ and  $(a+6)$
