Question

Pls helpp

does m^2-4 equal to (m-2)(m+2)?
and does m^2+4 equal to (m-2)(m+2) also then??when simplified

Answer 1

Answer:(m+2)(m+2)

Explanation:

The difference of two squares takes the form

`(x^(2) -y^(2) ) =(x-y)(x+y)`

`(x^(2) +y^(2) ) =(x+y)(x+y)`

`(m^(2) -4)=(m^(2) -2^(2) )=(m-2)(m+2)\\\\(m^(2) +4)=(m^(2) +2^(2) )=(m+2)(m+2)`

I hope you understand!
