Answer 1

What are you trying to find?

Answer 2

All roots

Answer 3

Can you help me?

Answer 4

Factorise the equation. That should give you your answers.

Answer 5

If it doesn't, use the quadratic formula.

Answer 6

Are no how to do that i am lose

Answer 7

Okay. You should have the quadratic formula with you somewhere. All you need to do is plug in the corresponding coefficients into the equation where ax^2 + bx + c = 0.

Answer 8

The quadratic formula is:
\[x= \frac{-b \pm \sqrt{b^2-4ac}}{2a}\]
In your equation,
\[x^2+8x-6=0\] a = 1, b = 8, & c = -6.
Can you put those values into the quadratic formula?
