Answer:  \bold{k=\dfrac{Fr^2}{qQ}}

<u>Step-by-step explanation:</u>

Isolate k by multiplying both sides of the equation by \dfrac{r^2}{qQ}

F=k\dfrac{qQ}{r^2}\\\\\\F\bigg(\dfrac{r^2}{qQ}\bigg)=k\dfrac{qQ}{r^2}\bigg({\dfrac{r^2}{qQ}\bigg)

\large\boxed{\dfrac{Fr^2}{qQ}=k}

Graph the equation
Lisa [10]
To find the root, replace y with 0
X^2-12x+35=0
A=1 B=-12 C=35
B^2-4ac=(-12)^2 -4(1)(35)
=144 -140
=4


x=(-b+/- square root of b^2 -4ac) /over/ (2a)
Plug in the numbers
x=-(-12) sqr (-12)^2 4(1)(35) / (2)(1)
X=12 +/-sqr 4 / 2
Positive outcome
x=12 + sqr 4 / 2
x=12+2/2
x=7 <— this one
Negative outcome
x=12-2i/2
x=6-i
Vertex: (6,-1)
