Answer:
288
Step-by-step explanation:
a = 9
b = -1
c = -8
b^2 * -4 * ( a * c )
Just filing in the numbers given above:
-1^2 * -4 * ( 9 * -8 )
1 * -4 * ( -72)
1 * + 288 = 288
Expand
(4a + 12 = 12 + 4a)
Cancel 4a on both sides
12 = 12
Since both sides are equal there are infinitely many solutions
Process of elimination, cross out d) no solution. But I would best go with C)
