Question

me ajudemmm a resolver essa equação do 2 grau incompleta. 25x² - 625=0

Answer 1

$25x^2 - 625=0$ =>  $25x^2= 625$ => $x^2 = \frac{625}{25}$ => $x^2 = 25$ => $x = \frac{+}{-}\sqrt{25}$ => $x = \frac{+}{-}5$

Answer 2

25(x^2) - 625 = 0
25(x^2) = 625
(x^2) = 625/25 = 25
x = + - RaizQuadrada (25)
x = + - 5
