(100)d^2-(57.3)d= 0

Question

solve for d.

yes...I just can't figure out what number I'd use to factor this and it got bumped to the next page.

I thought it was an easy question but...

Thanks

Answer 1

(100)d^2-(57.3)d= 0
factor out d.
d(100d)-57.3 = 0
solve for d. One is d = 0
100d = 57.3
d = 57.3/100 = 0.573.

Answer 2

darn...I feel so ________

Thanks Dr.Bob

Answer 3

I kept trying to factor out a number and the d, that's where I got cofused.
