Maths because im shit stupid

Op here find x

quadratic and do your own homework

You try it then man because I can't solve after quadratic and its not homewor its extra work

>>8881843
what do you mean you can't solve it after quadratic.?

Go ahead and try it or I'm just stupid

It's definitely solvable. You should get two answers. Throw out the negative one as you can't have negative time.

Anyone wanna help a brother put and do it because I've tried that

jesus fuck A= 4.9 B= 14.7 C = -8

[-B +/- sqrt (B^2 - 4AC) ] / 2A

x = .47 or - 3.47

>>8881876
I missed the negative in front of 4.9

>>8881857
>you can't have negative time
just wait until you learn about imaginary time

8=-4,9x2+14,7x |-8

-4,9x2+14,7x-8=0 |/-4,9

x2-3x-(80/49)

X1/2= -(-3/2)+/-sqrt((-3/2)2-(80/49))
X1=16/7
X2=5/7

i think ists wrong but where did i make the mistake
