Question

Explain how to use sign addition(+) and substraction (_) anywhere on factorize.

Answer 1

telling you about a trick which u can use to understand easily which sign to use I invented it

whenever there are +, +signs in the 2 brackets use the + sign 3 times

when there is +,- use +,-,-

when there is-,+ use -,-,-

when there is-,- use -,+,+

follow it u will be able to solve every sum of factorisation believe me
