Question

x² +2x-35 Alguem Me Ajuda ?

Answer 1

Delta= 4+140
Delta=144

X=-2+12/2
X'= 7
X''=2-12/2
X''= -10/2
X''= -5

Answer 2

x² + 2x - 35 = 0

Δ = b²−4ac
Δ = (2)²−4⋅1⋅(−35)
Δ = 4 + 140
Δ = 144


x = -b ± √Δ / 2.a
x = -2 ± √144 / 2. 1
x = -2 ± 12 / 2
x' = -2 - 12 / 2
x' = -14 / 2
x' = -7
x'' = -2 + 12 / 2
x'' = 10 / 2
x'' = 5

S = {-7, 5}
