X²-5X/3+1=2X+11/3

Answer 1

$\frac{ x^{2} -5x}{3+1}$ = $\frac{2x+11}{3}$
$\frac{ x^{2} -5x}{4}$ = $\frac{2x+11}{3}$
Multiplicando cruzado:
3x² - 15x = 8x + 44
3x² - 15x - 8x - 44 = 0
3x² - 23 - 44 = 0

Δ = (-23)² - 4 * 3 * (-44)
Δ = 529 + 528
Δ = 1057

x = $\frac{-(-23)+- \sqrt{1057} }{2*3}$
x ≈ $\frac{23+-32,51}{6}$

x' ≈ $\frac{23+32,51}{6}$
x' ≈ $\frac{55,51}{6}$
x' ≈ 9,25

x'' ≈ $\frac{23-32,51}{6}$
x'' ≈ $\frac{-9,51}{6}$
x'' ≈ 1,58
