Q:

What are the values of a, b, and c in the quadratic equation 0 = x2 – 3x – 2?a = , b = 3, c = 2a = , b = –3, c = –2a = , b = 3, c = –2a = , b = –3, c = 2

Accepted Solution

A:
For this case we have that by definition, a quadratic equation is of the form:[tex]ax ^ 2 + bx + c = 0[/tex]Where the roots are given by:[tex]x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2a}[/tex]We have the following equation:[tex]x ^ 2-3x-2 = 0[/tex]Then, according to the definition, the values are:[tex]a = 1\\b = -3\\c = -2[/tex]Answer:[tex]a = 1\\b = -3\\c = -2[/tex]
