Answer:
Plz don't delete...cuz im tryna help '-'
Step-by-step explanation:
25r²-100=0
25r^2 = 100
cuz the (-) will turn (+) when taken to the other side of the (=) sign
25r^2 = 100
divide both sides by 25
divide both sides by 25 then we get
r^2 = 4
r^2 = 2^2
now take the sqare root of both sides
r = 2
Answer:
[tex]25[r - 2][r + 2][/tex]
Step-by-step explanation:
[tex]25{r}^{2} -100 \\ 25({r}^{2} - 4) \\ 25(r - 2)(r + 2)[/tex]
