Explicação passo-a-passo:

$\mathsf{\Delta = b^2 - 4.a.c}$

$\mathsf{\Delta = (-12)^2 - 4.10.1}$

$\mathsf{\Delta = 144 - 40}$

$\mathsf{\Delta = 104}$

$\mathsf{V_{MIN} = \{-\dfrac{b}{2a};-\dfrac{\Delta}{4a}\}}$

$\mathsf{V_{MIN} = \{-\dfrac{(-12)}{2(10)};-\dfrac{104}{4(10)}\}}$

$\boxed{\boxed{\mathsf{V_{MIN} = \{\dfrac{3}{5};-\dfrac{13}{5}\}}}}$
