The discriminant of a quadratic equation is the value b squared -4 ac what is the value of the discriminant of 0=-2x+6x+13

108.

Step-by-step explanation:

Comparing the given equation with  the general form:

ax^2 + bx +   c = 0 ,

-2x^2 + 6x + 13 = 0 .

We see that  a = -2, b = 6 and c = 13.

So the discriminant

= b^2 - 4ac  

= (-2)^2 - (4 *-2 * 13)

= 4 - (-104)

= 4 + 104

= 108  (answer).

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
