studying for a test and I am pretty sure I am doing something wrong because I am not getting the answer I'm supposed to be getting could someone help me?
Solve by using the quadratic formula. Leave all answers in exact form.
Quadratic forumula = -b+or-√b^2 - 4ac / 2a
1.
m^2 + 20m = -51
2.
2t + 7t - 4 = 0
3.
1/6x^2 + 1/2x + 9 = 13
4.
2.4x^2 - 8.4x - 18 = 0
+36916 Make sure you are using the Quadratic Formula like this:
\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\)
and not as you wrote it in your question.......if you still get wrong answers , respond to this post....
for the first one a =1 b = 20 c = 51 (make sure your quadratic is in the form a x^2 + b x +c = 0 )
