Question

soma e produto de 3x² -18 - 15x​

Answer 1

$\boxed{\begin{array}{l}\sf Dada~a~equac_{\!\!,}\tilde ao~ ax^2+bx+c=0\\\sf a~soma~s~e~o~produto~p\\\sf das~ra\acute izes~\acute e~dado~por\\\sf s=-\dfrac{b}{a}\\\sf p=\dfrac{c}{a}\end{array}}$

$\boxed{\begin{array}{l}\sf 3x^2-16x-18=0\\\tt dados\begin{cases}\sf a=3\\\sf b=-16\\\sf c=-18\end{cases}\\\\\sf s=-\dfrac{-16}{3}=\dfrac{16}{3}\\\\\sf p=\dfrac{-18}{3}=-6\end{array}}$
