The discriminant is b^2-4ac
In this equation 9=a, 12=b, 4=c
Plugging into the formula
12^2-4(9)(4)=
144-324 =
-180 is the discriminant
Since the discriminant is a negative number there are no real roots
Answer:
Step-by-step explanation:
-1 1 3 5 7 9 11
That's the answer. If you need a method or a formula, that's a little harder.
L = a + (n - 1)*d
a = -1
L = 11
n = 7
or n is the hard part. If you have 5 means, then you have 6 spaces. So n must be 7 in all
11 = -1 + (7 - 1)*d add 1 to both sides. Combine the brackets
11+1 = -1+1+ 6*d
12 = 6d divide by 6
12/6 = d
2 = d
What this tells you is that each term has 2 added to it to get to the next one.
10v + 6 = -54
Subtract 6 to both sides
So 10v + 6 = -54
10v - 6 = -6
10v = -60
Divide both sides by 10
