Question

8x squared - 11x=-3 I need to find the number of real solutions.

Answer 1

like this?
8x^2 - 11x = -31

if so,
we will need to use the quadratic equation:
\[\frac{ -b \pm \sqrt{b^2 - 4ac} }{ 2a }\]

Answer 2

do you know how to pick out the values for a, b, and c from the equation you posted?

Answer 3

its not 31 but its equals 3

Answer 4

8x^2 - 11x = -3 ?

Answer 5

yes

Answer 6

8x^2 - 11x = -3
becoms
8x^2 - 11x + 3= 0
can you pick out the a, b, and c values of your equation looking at this similar form?
ax^2 + bx + c = 0

a=?
b=?
c=?
