Answer 3

See that denominator on the left
Cross multiply and take it to the right and then bring all the terms to the left side of the equality

Answer 4

x^2 = 5.74 x 10^-4 * .122-x

Answer 5

Then x^2 - 5.74 x 10^-4 - .122-x ?

Answer 6

Yeah correct so u have this-

\(x^2-(5.74 \times 10^{-4})(0.122-x)\)

Now simplify the brackets

Oh that is where I was messing up. I have to distribute the 5.74 x 10^-4.

Answer 9

So that is 7 x 10^-5 - 5.74 x 10^-4

Answer 10

Then I distribute the negative.
