Find the Sum and Product of the Roots of the Quadratic Equation 4x^2-12x+9=0

$4 x^{2} - 12 x + 9 = 0$

Find $a$ , $b$ , and $c$ .

Once the quadratic is in standard form, the values of $a$ , $b$ , and $c$ can be found.

$a x^{2} + b x + c$

Use the standard form of the equation to find $a$ , $b$ , and $c$ for this quadratic.

$a = 4$ , $b = - 12$ , $c = 9$

Substitute the values into the sum of roots formula $- \frac{b}{a}$ .

Divide $12$ by $4$ .

$3$

List the results.

Sum of the roots is $3$

Product of the roots is $\frac{9}{4}$
