Answer:
-7
Step-by-step explanation:
30-16= -5n +3n
14 = -2n
multiplying both by half,u have -
7 = -n
multiply both by -1
7 = n
36. 9-3=6x6=36
c=3 6x(9-c) do the parentheses first then multiply. the parentheses is 6 then multiply it with 6 =36
The roots of the equation is x = 4.56 OR x = 0.44
<h3>Quadratic equation</h3>
From the question, we are to determine the roots of the given equation
The given equation is
x² -5x +2 = 0
Using the formula method,

In the given equation,
a = 1, b = -5, c = 2
Putting the values into the formula,



OR 
OR 
OR 
x = 4.56 OR x = 0.44
Hence, the roots of the equation is x = 4.56 OR x = 0.44
