What Is The Discriminant Of 9x2 2 10x
What is the difference between 9x2 + 2 = 10x? 3
A) - "356
B) - 172
C) 28
D) 72
This c.
First, write the equation in the form: Ax 2 + Bx + C = 0 (square equation).
We do this by subtracting 10x from both sides (to bring it to the other side).
9x 2 + 2 = 10x
9x 2 10x + 2 = 10x 10x
9x 2 10x + 2 = 0
Now discrimination: b 2 4ac
The square equation is Ax 2 + Bx + C = 0.
Here A = 9, B = 10 and C = 2, so add them ...
(10) 2 4 (9) (2)
= 100 4 (18)
= 100 72
What Is The Discriminant Of 9x2 2 10x
What Is The Discriminant Of 9x2 2 10x
9x 2 10x + 2 = 0
The discriminator is b 2 4ac.
Or
a = 9
b = 10
c = 2
About what
(10) 2 4 (9) (2) =
100 72 =
28
First, write the equation on the form.
9x 2 10x + 2 = 0. You
The difference is (10) 2 4 * 9 * 2 = 100 72 = 28
Cice C.
