Question

Please help!!!I have 0 to none idea what’s going on

Answer 1

Given:

`y=3x^2+2px+4q`

Which has no real roots.

To prove:

`p^2<12q`

Step-by-step explanation:

Since it has no real roots.

So, the discriminant becomes,

`\begin{gathered} D<0 \\ \Rightarrow b^2-4ac<0 \end{gathered}`

Substituting the below values in the inequation.

`\begin{gathered} a=3 \\ b=2p \\ c=4q \end{gathered}`

We get,
