Question

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

Answer 1

0

Answer 2

thank you

Answer 3

Do you understand how to get that answer?

Answer 4

There are two real zeros. They are multiples of x=-1/2

So x=-1/2 is a solution.\[(x+1/2)^{2}\]Check

\[-8(-1/2)^{2}+-8(-1/2)-2=0\]\[-8(1/4)+4-2=0\]\[-2+4-2=0\]\[0=0\]
