Solve all values of X by factoring:

Factoring not possible

x = -3 + sqrt(7), -3 - sqrt(7)

Or,

x = 0, -8

Step-by-step explanation:

x² + 6x + 4 = 2

x² + 6x + 2 = 0

Doesn't have rational roots

Quadratic formula:

By - 4AC = 6² - 4(1)(2) = 28

Sqrt(28) = 2sqrt(7)

x = [-6 +- 2sqrt(7)]/2

x = -3 +- sqrt(7)

x = -3 + sqrt(7), -3 - sqrt(7)

If the equation is:

x² + 6x + 4 = -2x + 4

x² + 8x = 0

x(x + 8) = 0

x = 0, -8

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?

step-by-step explanation:

the answer is b.
