Question

10x²-x-3=0 acha o valor de delta

Answer 1

10x² - x - 3 = 0
Δ = (-1)² - 4.10.(-3)
Δ = 1 - 1 200
Δ = - 1 199

Answer 2

$\large\sf{} {10x}^{2} - x - 3 = 0 \\ \begin{cases}a = 10 \\ b = - 1 \\ c = - 3\end{cases} \\ \\\large\sf{} \Delta = \left ( - 1\right)^{2} - 4 \times 10 \times \left ( - 3\right) \\\large\sf{}\Delta = 1 - 4 \times 10 \times \left( - 3\right) \\ \large\sf{}\Delta = 1 - 1200 \\ \large\sf{}\Delta = -1199$
