Question

-3x²-2x+2=0 formula de baskara preciso do calculo obrigaduu​

Answer 1

Explicação passo-a-passo:

Ax² ± Bx ± c

A = -3

B = -2

C = 2

Δ = b² -4ac

Δ = -2² -4 × (-3) × 2

Δ = -4 + 12 × 2

Δ = -4 + 24

Δ = 20

Bhaskara: $\frac{-b±\sqrt{Δ}}{2a}$

Bhaskara: $\frac{-(-2)±\sqrt{20}}{2×(-3)}$

Bhaskara: $\frac{2±\sqrt{20}}{-6}$

$\Large\text{ \boxed{X1: \frac{2+\sqrt{20}}{-6}} }$

$\Large\text{ \boxed{X2: \frac{2-\sqrt{20}}{-6}} }$
