Question

demonstrate how your quadratic equation expression is solved by the Quadratic Formula. Explain your steps x²+8x+2=0

Answer 1

You need to factor

Answer 2

Solutions are: -.25 and -7.74

Answer 3

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

Answer 4

Actually mridrik is right, you should use the quadratic formula

Answer 5

the opposite of b (8) = -8

Answer 6

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

Answer 7

then divide by 2

Answer 8

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)
