( simultaneous equations)
daser333 [38]

Answer:

See method below.

Step-by-step explanation:

m/n + n/3 = 2

2/m + n = 4    

First  eliminate the fractions by multiplying the first equation by 3n:-

3m + n^2 = 6n...........(1)

and the second equation by m:-

2 + mn = 4m..............(2)

Now we solve using substitution:-

From equation  (2):-

4m - mn = 2

m = 2 / (4 - n)

Now substitute for m in equation (1):-

6/ (4 - n) + n^2 = 6n

6 + n^2(4 - n) = 6n(4 - n)

6 + 4n^2 - n^3 = 24n - 6n^2

n^3 - 10n^2 + 24n - 6 = 0

This will not factor so we could solve this using graphical software.

To find the values of the variable m we substitute the found values of n into one of the original equations and solve for m.

Solve the quadratic equation for x in the simplest equation -6x^2+15x+9=0
Alexus [3.1K]

Answer:

x = 3, -1/2

Step-by-step explanation:

Use the quadratic formula:  x = [-b ± √b² - 4ac]/2a

The square root sign should be over the entire expression b² - 4ac

In this problem, a = -6, b = 15, and c = 9

So, putting in those values, we get x = -15 ± √225+216, all divided by -12

Simplifying further, we get -15 ± 21 all divided by -12, or -36/-12 = 3 OR

6/-12 = -1/2
