Question

Ummm, this is due in like 2 minutes..

Answer 1

x = - 3 square root +-7

Explanation:

Common factor:

(6r^2 +6 r + 12) /6= 0/6

r^2 +r+2 = 0

r^2 +1 r = -2

Square half of r term.

[1*(1/2)] = 9

Add 9. To both sides

x^2 + r + 9 = -2 + 9

x^2 + 2 + 9 = 7

(x + 3)^2 = 7

Square root of both sides =

x + 3 = square root of +-7

x = -3 +- sq.root 7

Answer 2

r= −1−i√7/2,

r= −1+i√7/2
