Question

How many real number solutions does the equations have ?

y=5x^2+2x-12
-one
-two
-infinitely many solutions
-no solutions

Answer 1

are you wanting to see a graph.... or na

Answer 2

noo I just need the awnser ... .and expain ...don't know how to do it

Answer 3

Oh, the answer is 'one'

y=5*x^2+2*x-12 simplifies to y-5*x^2-2*x+12=0

Answer 4

x=0, y=-12
x=1, y=-5
That is just two of many solutions.

Answer 5

look at 5*x^2+2*x-12
moved these terms to the left 5*x^2-2*x+12
which makes it become y-5*x^2-2*x+12=0

thats explained

but the answer is 'one'

Answer 6

thanks ...blahblahblah how good are you at math ??

Answer 7
