For this case we have the following quadratic equation:

[tex]x ^ 2 + 7x + 9 = 3[/tex]

We must rewrite the equation as:

[tex]ax ^ 2 + bx + c = 0[/tex]

So:

Subtracting 3 from both sides of the equation we have:

[tex]x ^ 2 + 7x + 9-3 = 0\\x ^ 2 + 7x + 6 = 0[/tex]

So we have to:

[tex]a = 1\\b = 7\\c = 6[/tex]

Answer:

[tex]x ^ 2 + 7x + 6 = 0[/tex]
