Question

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

Answer 1

1) subtract 5x from both sides
2) set the equation in order ax^2+bx+c=0
3) plug in numbers inside the discriminant, which is b²-4(a)(c)

Answer 2

okkk

Answer 3

i did step 3

Answer 4

and what do you get ?

Answer 5

wait a sec im wrong

Answer 6

wait the problem was 3x^2-2=5x

Answer 7

yes, and when you subtract 5x from both sides you get

\(\LARGE\color{blue}{ \bf 3x^2-5x-2=0 }\)

Answer 8

yess i did that too

Answer 9

so then do i solve from there

Answer 11

I am sure you have been solving quadratic equations using quadratic formulas before, haven't you ?

Answer 12

yep, or good old factoring

Answer 13

yess

Answer 14

no... he needs the discriminant.
