Question

Alguem pode mim ajuda 5x²-43x=+24=0

Answer 1

5x² - 43x + 24

↓ ㅤ ↓ ㅤ ↓

a ㅤ b ㅤ c

Δ = b² - 4ac

Δ = 43² -4 × 5 × 24

Δ = 1.849 -20 × 24

Δ = 1.849 - 480

Δ = 1.369

ㅤ

ㅤ

X = $\frac{-b ± \sqrt{Δ}}{2a}$

X = $\frac{-(-43) ± \sqrt{1.369}}{2.5}$

X = $\frac{43 ± 37}{10}$

X1 = $\Large\boxed{0,6}$

X2 = $\Large\boxed{8}$
