Question

X^2 +7x +9=3 written as ax^2+bx+c=0

Answer 1

For this case we have the following quadratic equation:

$x ^ 2 + 7x + 9 = 3$

We must rewrite the equation as:

$ax ^ 2 + bx + c = 0$

So:

Subtracting 3 from both sides of the equation we have:

$x ^ 2 + 7x + 9-3 = 0\\x ^ 2 + 7x + 6 = 0$

So we have to:

$a = 1\\b = 7\\c = 6$

Answer:

$x ^ 2 + 7x + 6 = 0$
