Answer:
(-11 +/- sqrt 21) / 10
or
-0.64 , -1.56 to the nearest hundredth.
Step-by-step explanation:
9v^2 + 11v + 5 = 4v^2
5v^2 + 11v + 5 = 0
Using the quadratic formula:
v = [ - 11 +/- sqrt(11^2 - 4*5*5) ] / 2*5
= (-11 +/- sqrt 21) / 10
= -0.64 , -1.56 to the nearest hundredth.
Answer:

Combine like terms in [1] ,we have;
Simplify:

Therefore, the simplified form of
is, 
The answer is 120 * sqrt of 2
3 * sqrt of 50 * 8 = 24 * sqrt of 50
24 * sqrt of 50 simplifies to 120 * sqrt of 2
