Question

Solve the following equation for t:

h= -64t^2+at+g

 

b) 0.2x^2-1.2x-0.2=0

Answer 1

Solve the following equation for t:
h= -64t^2+at+g

 

-64t^2+at+g-h = 0; now just use the quadratic formula, substituting as follows:

For a, use -64   for b use letter a (coefficient of t)   for c use (g-h).  It's not going to be pretty!

 

b) for the second equation, it's best to CLEAR DECIMALS by multiplying all terms by five, then you have

x² - 6x -1 = 0 and then you use the quadratic formula since this is not factorable.
