Answer:
K<-12
Step-by-step explanation:
+ For that, we need the delta negatif.
+ The delta= b^2-4ac=12^2-4(-3)(k)=144+12k<0
Then, 12k<-144 (divise both sides by 12)
we have k<-12
Or an other way:
-3x^2+12x+k=0 (divise both sides by -3)
x^2-4x-k/3=0
x^2-4x+4 -4-k/3=0
(x-2)^2=4+k/3
Now , we need 4+k/3<0, k/3<-4 or k<-12
Hope you understand.

<h3>What are Algebraic equations?</h3>
With one exception, algebraic equations are essentially algebraic expressions.
An = sign is required in all algebraic equations.
No matter what kind of equation it is, all equations use the = sign.
The next topic is algebraic expression, which lacks the operators =,,, >, and.
To put it simply, there is no comparison between two terms in an algebraic statement.
Algebraic expressions frequently use terms like polynomial and square root.
So you now recognize the distinction between the two?
1) An algebraic equation has the symbol =, and 2) an algebraic expression lacks any comparison symbols (such as > and =).
As per the question:

55/9 + 10/3 = 85/3
(55m+30m)/9 = 85/3
85m/9 = 85/3
85m = (85*9)/3
85m = 85*3
m = (85*3)/85
∴ m = 3
