Question 802559: Please answer many as you can - Thank You

Solve the equation
5) 2b - 5 over b-2 minus 2 equal 3 over b + 2
2b-5/b-2 - 2 = 3/b+2
6) Radical -45+14n = n
7) -n + radical 16n+19 = 2
Thank You again

5) 2b - 5 over b-2 minus 2 equal 3 over b + 2

LCD =

-4b=-4
b=1
-----------------

6) Radical -45+14n = n

square both sides

n(n-9)-5(n-9)=0
(n-9)(n-5)=0
n=9 OR 5
------------------
7) -n + radical 16n+19 = 2

square

Find the roots of the equation by quadratic formula
-1
a= 1 b= -12 c= -15
-60
b^2-4ac= 1 -
b^2-4ac= 61 = 7.81

7.81
x1=( 1 + )/ 2
x1= 4.41 ) /
x2=( 1 -7.81 2
x2= -3.41
