For denominator you have to multiply the two binomials.
(1-x)(2-x)
Multiply 1 times the terms in the second binomial then multiply -x times the terms in the second binomial.
2 -x -2x +x^2
simplify to 2 -3x + x^2
rewrite in descending order to get
x^2 -3x + 2
Mulitply that by 49.7 and that answer will be equal to 2x^2
Subtract 2x^2 from both sides to get your answer.
I did this assuming that the (1.00-x)(2.00-x) is all under the division sign and the whole thing is in the denominator.
Same kind of problem. How to rearrange to put an equation in quadratic form.
Example I'm given is
49.7= 2x^2 / (1.00-x)(2.00-x)
which should come out to .920x^2 -3.0x + 2.0
but I can't figure out exactly how to get to there, especially how to get the x squared number.
