Question

Help Please !

What is the number of real solutions ?

12x^2-11x=11

A. Two real solutions
B. one real solution
C. cannot be determined
D. no real solutions

Answer 1

Tima, the apply the quadratic formula.

Answer 2

12x^2 -11x - 11 = 0
x = -b +- √b^2 -4ac

Answer 3

plug the values in and find the solutions

Answer 4

Use the power within!
But first check the discriminant :)

Answer 5

oh yeah that works too
b^2 - 4ac

Answer 6

Guys just give me the answer, im timed!

Answer 7

Then explain after words. lol

Answer 8

-.-

Answer 9

I'm no longer glazing your donut!
it's two real solutions.

Answer 10

That urge to report..

Answer 11

Hehe Thanks Shamil. LOL

And Luigi Im not gunna give a medal cuz of that.-.-

Answer 12

Now, you are going to stay and read my explanation. okay?

Answer 13

b^2 - 4ac

If discriminant > 0 quadratic equation will have two real roots.
If discriminant = 0 quadratic equation will have two equal roots.
If discriminant < 0 quadratic equation will have no real roots (imaginary)

Answer 14

so in this case (-11)^2 - 4(12)(-11) = 121 + 528
= 649
the discriminant is positive.

Answer 15

Pfft, who needs medals?

Answer 16

so it has two real roots.

Answer 17

UNDERSTAND TIMA?

Answer 18

LATER SHAMIL. Ill Read everything you wrote I rpomise.
