Question

How many real number solutions does the equation have?
-8x^2 - 8x - 2 = 0

A: One solution
B: Two solutions
C: No solutions
D: Infinitely many solutions

Answer 1

look at the graph above
how many times does it cross x axis ?

Answer 2

once

Answer 3

Yes clearly it becomes 0 only once
so only one solution

Answer 4

You can also use the discriminant, \(b^2-4ac\) to find the # of real and imaginary solutions once you simplify the equation.
