Question

It is asking me to insert parentasies

Answer 1

Parenthesis is () so if they said to put () it means to put those on a certain equation or numbers.
Like: 4+5-7 put with parenthesis it is (4+5) -7 or 4+ (5-7)
It's mostly in PEMDAS (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction) problems and algebra equations!

Answer 2

If you mean for factoring, then you must take the common factor (term) out of the equation then have the rest out of what you divided
