Question

i need to find the solution set: 8x^2-6x-9=0

Answer 1

Have you tried the general solution to the quadratic equation?

Answer 2

I have tried it but im kind of confused because i missed 3 lessons so its kind of hard to understand

Answer 3

\[x = -b \pm \sqrt{b ^{?}}\]

Answer 4

\[x = (-b \pm \sqrt{b ^{2}-4ac})/(2a)\]

Answer 5

Disregard the first equation. This is for ax^2 + bx + c = 0.

Answer 6

The a,b,c lines up exactly with your question. Just substitute and solve.

Answer 7

How far have you gotten?
