Question

12. Using the discriminant, how many real number solutions does this equation have?
3x2 – 2 = 5x

@ShadowLegendX

Answer 1

do you know the discriminant?

Answer 2

no

Answer 3

you need to arrange your equation into proper format first
Ax^2 + Bx + C = 0

Answer 4

ok

Answer 5

i did that

Answer 6

write it down here so I can see if you did it correctly

Answer 7

ok hold on

Answer 8

um.. jus a sec

Answer 9

do i substutute

Answer 10

substitute what?

Answer 11

ohhh nvm im not suppose to do that

Answer 12

do i use PEMDAS

Answer 13

turn your equation into zero
\[3x^2-5x-2 = 0\]

Answer 14

okk want me to do it lik that

Answer 15

so is 3x^2-5x-2=0 the answer

Answer 16

not yet
it is just the beginning of figuring out the discriminant

Answer 17

ok

Answer 18

do you know the quadratic formula?

Answer 19

yess kinda

Answer 20

start identifying which is A, B and C
these are the coefficients of the equation

Answer 21

ok

Answer 22

do you know what coefficients are?

Answer 23

yess

Answer 24

do u know the answer

Answer 25

is the answer 2

Answer 26

@mathstudent55

Answer 27

show me the solution how you got 2

Answer 28

i jus used the link u showed me thas all.

Answer 29

I got 2 because its a coefficient

Answer 30

wait coeffients are lik the ones with no exopnent or no

Answer 31

A = 3
B = -5
C = -2

coefficients are the number in front of the variables in an expression.

Answer 32

ok i got that

Answer 33

so wats the answer

Answer 34

use the discriminant formula I provided

Answer 35

ok well i got 2 is that right

Answer 36

can you write it down and show me how you got 2

Answer 37

well i jus guessed

Answer 38

am i right

Answer 39

no

Answer 40

ohhh lol well can u tel me the answer

Answer 41

b^2 -4ac
(-5)^2 - 4(3 * -2)

Answer 42

thas the answer

Answer 43

thanx @nincompoop nd fan me lol u neva did

Answer 44

poor phoebe
