Ответ:
its 4 because 3(4) = 12 then subtracting (2+4=6) so then 12-6= 6 :)

Answer :![a = -4, b = 5, c = -2](/tpl/images/0272/3706/0f769.png)
We need to find the values of a, b, and c in the quadratic equation![0 = 5x - 4x^2 - 2](/tpl/images/0272/3706/f3a71.png)
The general form of quadratic equation is![ax^2 + bx + c =0](/tpl/images/0272/3706/0260b.png)
First we arrange the equation in order. x^2 should come first
The coefficient of x^2 is the value of 'a' = -4
The coefficient of x is the value of 'b' = 5
The constant is the value of 'c' = -2
So a = -4, b=5 and c= -2
