Question

resolva esta equação 5/x=4-3x-5/x

Answer 1

5........4 - 3X -5
_ = ________
X ..............X

5.......-3X -5 + 4
_ = ________
X................X

5.......- 3X - 1
_ = ______
X............X

5X = X (-3X - 1)

5X = - 3X^2 - X

3X^2 + 5X + X = 0

3X^2 +6X =0

3X (X + 2) = 0

3X' = 0 => X' = 0/3 => X' = 0

X" + 2 => X" = - 2
