Question

Would (a+7)² or a²+49 be the best answer to
a²+14a+49, for completly factoring?

Answer 1

(a+7)^2 = a^2 + 2*7*a + 7^2 = a^2 + 14a + 49

Answer 2

TY again!!!!

Answer 3

coolsector has the correct answer, however turning
\[(a+7)^2\] into
\[a^2+14a+49\] is called "multiplying" not "factoring"
"factoring" means rewriting
\[a^2+14a+49\] as
\[(a+7)^2\]
