Find the Sum and Product of the Roots of the Quadratic Equation 18-10x+x^2=0

$18 - 10 x + x^{2} = 0$

Step 1

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.

$a = 1$ , $b = - 10$ , $c = 18$

Step 2

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

Divide $10$ by $1$ .

$10$

Step 3

Substitute the values into the product of roots formula $\frac{c}{a}$ .

Divide $18$ by $1$ .

$18$

Step 4

List the results.

Sum of the roots is $10$

Product of the roots is $18$
