Pls helppDoes 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:(m+2)(m+2)

Step-by-step 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!
