You need to factor

2. anonymous

Solutions are: -.25 and -7.74

3. anonymous

Using the quadratic formula which is $(-b \pm {\sqrt{b^2-4ac}})/2a$

4. anonymous

Actually mridrik is right, you should use the quadratic formula

5. anonymous

the opposite of b (8) = -8

6. anonymous

plus or minus sqrt(b^2-4ac) the square root of (8^2-4(2)(1)) = sqrt(56)

7. anonymous

then divide by 2

8. anonymous

your two solutions are 8+sqrt(56) = 8 + 2sqrt(14) divided by two is 4 + sqrt(14) since we have to do plus or minus the other solution is 4 - sqrt(14)
