i have to determine the number of solutions of this quadratic equation and solve it

Question

anonymous · Answer

whats the equation

anonymous · Answer

$$-4y ^{2}+3=-7y$$

anonymous · Answer

Well let's set that = 0 first (and, for ease, have it on the side so y^2 is positive)

anonymous · Answer

and it should be 2 answers if you are using the quadratic equation

amistre64 · Answer

the number of solutions?

anonymous · Answer

yeah it's an online assignment so once I determine how many solutions and whither they are real or not I select that and type in the answers

anonymous · Answer

it's either 2 different real solutions or 2 non-real solutions

amistre64 · Answer

the solutions are infinite and create a parabolic curve on a graph....

anonymous · Answer

Ugh, horrible, horrible radical solutions. I'm out.

And isn't it just a quadratic with 2 (yes, I checked, there should be 2 real ones)

amistre64 · Answer

or am I confusing definitions......

amistre64 · Answer

if it equals zero, then there is at most 2 real solutions...youre right :)

anonymous · Answer

Sorry if i was confusing in my explanation. Basically i just need to solve that now. THanks

amistre64 · Answer

-1(4y^2 -7y -3) = 0

4y^2 -7y -3 = 0

7/8 +- sqrt(49+48)/8

anonymous · Answer

ok so the 49 +48 makes 97. would this be put over 8, and the 7 is over 8 as well?

amistre64 · Answer

yes.
