You can put this solution on YOUR website! hello fellow imgurian, Mewmus here.
we start by taking ax^2 + bx + c = 0, standard form of quadratic formula
now, the second part, the quadratic formula:
x = -b +- sqrt of b^2 - 4(ac) divide the whole thing by 2a
your equation is 3k^2 - 1k - 9 = 0
this translates into k = -(-1) +- sqrt (-1)^2 - 4 (3)(-9) divide the whole thing by 2(3)
N will = 1
D will = 109
M will = 6
solutions are (according to algebra.com) k=1.90671775148509,k=-1.57338441815176

Thank you! :)
The quadratic equation formula, based on the quadratic equation: , is:
The quadratic equation formula, based on the quadratic equation: , is:
Your quadratic equation: , so we get: ====>
Can you now tell what N, D, and M are? You should be able to!
The more difficult part is now done for you, so use your calculator to determine the answer to B).
