Ganito lang po yan.
step 1. square root of r^2 is r.
step2. square root of 100 is 10.
step 3. walang middle term kya automatic zero.
step 4. just look for the sign sa gitna, negative.
step 5. pag ganyan po ang sign tapos dalawang term lang meron, r^2 and -100., + and - po ang sign pag i factor.
step 6. then i combine po yun lahat sa factoring.
(r+10) (r-10) =0
so, r = 10 and r = -10.

note: d po ito ang complete explaination kaya feel free to ask po f paano nkuha yung mga sinabi ko.

R² - 100 = 0

r² = 100

 \sqrt{ r^{2} }  = \frac{+}{-}  \sqrt{100}

r = +10,  -10
