(quadratic formula) (irrational level 1)

solve the equation for all real solutions in simplest form.

9v^2+11v+5=4v^2

(-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.
