Question

0.05x^2 -x+1 = -1+1 Im trying to figure out what would be my next step to finding the solutions through Completeing the square

Answer 1

0.05x^2 -x+1 = -1+1
0.05x^2 -x+1 = 0
x^2 -20x+20 = 0

then using quadratic formula

do you know??

Answer 2

how did you get that third step?

Answer 3

ok

x = (-b +- sqrt(b^2-4ac)/2a
x=(-(-20) +- sqrt((-20)^2 - (4 x1x 20))/2
x = (20 +- sqrt(320))/2
x = (20 +- 17.88)/2

So

x = (20 + 17.88)/2 = 18.94

or

x = (20 - 17.88)/2 = 1.06

Answer 4

divided all by 0.05 for third step @FlyinSolo_424

Answer 5

0.05x^2 -x+1 = -1+1
0.05x^2 -x+1 = 0
((0.05x^2)/0.05) -(x/0.05)+(1/0.05) = (0/0.05)
x^2 -20x+20 = 0

Answer 6

Thank you So much For explaining I did it once I got that little thing nd I got the same anwser

Answer 7

welcome @FlyinSolo_424 , good job :)
