When a number is added to six times its square, the result is twelve. Find the number.
7nadin3 [17]
Let's represent our number as x.
x is being added to 6 * x², and it equals 12
x + 6x^{2}=12\\6x^{2}+x-12=0
Factor:
6x^{2}+x-12=0\\(2x+3)(3x-4)=0
Solve for x:
(2x+3)=0\\2x=-3\\x=\frac{-3}{2}\\\\(3x-4)=0\\3x=4\\x=\frac{4}{3}

Therefore, x = -3/2 and 4/3.

Let a represent the length of where the bird was sitting to the oak tree

let b represent the height of the tree

let c represent the length at which the bird flew

by pythagoras theorem

c²=a²+b²

b²=c²-a²

b =  \sqrt{ {c}^{2} -  {a}^{2}  }

subtitute in the values

b =  \sqrt{ {15}^{2} -  {9}^{2}  }

b =  \sqrt{225 - 81}

b =  \sqrt{144}

b = 12
