Y=3x²+3x+1,find the value of the discrimination​
Rufina [12.5K]

Answer:

Step-by-step explanation:

a = 3

b = 3

c  = 1

Discriminate = sqrt(b^2 - 4ac)

Discriminate = sqrt(9 - 4*3*1)

Discriminate = sqrt(9 - 12)

Discriminate = sqrt(-3)

What negative value means that there are no real roots and the y intercept = 1. You should always graph this kind of question, which I am doing for you. I use Desmos which is a very handy program.

You should notice that the minimum is above the x axis. That means there are no real roots, just as the discriminate tells you.

Answer:

10. 108

11. 1,100

<em><u>12.</u></em>

-11 + 13 = 2

35 + -5 = 30

6 + (-3) +4 + 6 + (-5) = 8

5 + (-4) + (-9) + 8 = 0

(6) (8) = 48

(-2) (9) = -18

(-11) (-4) = 44

-256 divided by 0 = 0

-96 divided by +3 = -32

-36 divided by 3 = -12
