Answer:

x= -22d/44 x = -48d/44 is your answer

where d =2x

Explanation:

22d²- 35d + 12 = -3d²

22d²- 35d + 12 +3d²

25d²- 35d + 12 = a b c formula= - b-/+ / b^2 - 4 ac / 2a

= -35d -+/ 35^2 - 4 *22d *12 / 2*22d

= -35d -+/1225d-4 (22) (12) /44d

= -35d -+/1225d- (88) (12) /44d

= -35d -+/1225d- (1056) /44d

= -35d -+/169d- /44d

=-35d -/+ 13d /44 x= -22d/44 x = -48d/44

The discriminant b2−4ac>0

so, there are two real roots.
