The steps to derive the quadratic formula are shown below:

alukav5142 [94]

Answer:

(c) x plus b over 2 times a equals plus or minus the square root of the quantity b squared minus 4 times a times c all over the square root of 4 times a squared

Step-by-step explanation:

The next step is to take the square root of both sides of the equation. It can help to show the intermediate steps.

<h3>Result so far</h3>

The last step shown in the derivation so far is ...

$x^2+\dfrac{b}{a}x+\dfrac{b^2}{4a^2}=-\dfrac{4ac}{4a^2}+\dfrac{b^2}{4a^2}$

The left side of the above expression can be written as a square, and the right side can be written over one denominator. Then the square root is taken as the next step.

$\left(x+\dfrac{b}{2a}\right)^2=\dfrac{b^2-4ac}{4a^2}\\\\\sqrt{\left(x+\dfrac{b}{2a}\right)^2}=\sqrt{\dfrac{b^2-4ac}{4a^2}}\\\\\boxed{x+\dfrac{b}{2a}=\pm\dfrac{\sqrt{b^2-4ac}}{\sqrt{4a^2}}}\qquad\text{"next step"}$

Johnny is paid a one-time fee of $245.00 for all his jobs. His uncle also pays him $20.00 for each hour that he works. After all

Free_Kalibri [48]

Answer:

100 hours

Step-by-step explanation:

If Johnny is paid 245.00 as a one time fee for all his jobs then the total money he is paid is 2245.00

We need to separate the hourly fee from the one-time fee so we subtract 245 from 2245. This leaves us with 2000 dollars.

We know that he will be paid 20 dollars per hour so we need to divide 2000 by 20. This leaves us with 100.

<h2>Therefore Johnny worked 100 hours</h2>
