good evening! Can someone please answer this, ill give you brainliest and your earning 50 points. Would be very appreciated.

Answer:
A Trinomial expression has 3 terms.
If it has degree 2, then the exponent of the leading term will be 2.
If the leading coefficient is -5, then the leading term will be [tex]-5x^2[/tex]
Written in standard form: [tex]y=-5x^2+bx+c[/tex]
We are not given any information about the coefficients of the remaining two terms, so we can substitute any values for these:
Therefore, [tex]y=-5x^2+3x+2[/tex]
Note the standard form
Here we have
So
the expression is
