## anonymous one year ago When the following quadratic equation is written in general form, what is the value of "c"? -3/4x^2 + 2 = 0 is it -2?

1. Michele_Laino

the general form of a quadratic equation is: $a{x^2} + bxy + c{y^2} + dx + ey + f = 0$

2. Michele_Laino

where a, b, c, d, e, and f are real parameters

yes!

5. Michele_Laino

if we consider a quadratic equation in one variable: $a{x^2} + bx + c = 0$ then we can rewrite your equation as follows: $\frac{3}{4}{x^2} - 2 = 0$

6. Michele_Laino

or: $3{x^2} - 8 = 0$

7. anonymous

add 8 divide by 3? or no

8. Michele_Laino

no, since we have rewritten your equation using integers parameters

9. Michele_Laino

so, I think that a possible choice, can be this: a=3, b=0, c=-8

thanks i got the answer c = -8 :)
