C -2 because of the thanos
A quadratic equation has the general formula expressed as:<span>
ax^2 + bx - c = 0
This equation can be solved by the quadratic formula which is expressed as:
x = ( -b (+ or -) √(b^2 - 4ac) / 2a
From the given equation,
a = 9
b = -54
c = -19
x = ( -(-54) (+ or -) √((-54)^2 - 4(9)(-19)) / 2(9)
x1 = 19/3
<span>x2 = -1/3</span></span>
K I think that it is okay because it would be 10
Ummmm it’s already solved lol do u mean on a graph or something
