Question

Which of the following shows a factor of 100b^2-144a^4

Answer 1

Answer: Both:
_____________________
[A]: 10b − 12a ; AND:
_________________________________
[B]: 10b + 12a ;
_________________________________
Since: " 100b² − 144a⁴ " factors into:
_________________________________
" (10b − 12a) (10b + 12a) " .
_________________________________

Answer 2

(10b-12a^2)
(10b+12a^2)
This is the factorization
