Can someone please help me ASAP​
Sonja [21]

Answer:

x^2 + 5n = 4mx

=> x^2 - 4mx + 5n = 0

D=0 (since one root then roots are equal)

b^2-4ac = 0

(-4m)^2 - 4(1)(5n) = 0

16m^2 - 20n = 0

16m^2 = 20n

8m^2 = 10n

4m^2 = 5n

hope it helps.......

I'm going to take a guess regarding what you meant to type in:

<span>3x-9 X +6x+5
E(x)= ------- × -------------
2 2
X -9 X +5x+6

                            3(x+3)        6x+5
becomes  E(x) = ----------- * ------------
                             x-9             5x+6

This cannot be reduced.

Try again to share this problem.  Thank you.
