Question

xao quadrado + 100x-7500=0

Answer 1

Olá!!



X²+100X-7500 = 0


Δ = b²-4.a.c
Δ = 100²-4.1.(-7500)
Δ = 10.000+30.000
Δ =40.000


X = -b +/- √Δ
     -------------
           2a



X = -100 +/- 200
    --------------------
                 2

X' = 100/2
X' = 50

X'' = -300/2
X'' = -150



S = {50 e -150}
