Which is the solution to the following equation?
4x^2-12x+9=5

We assume that
if xy=0
x and y=0

first make it equal to zero

minus 5 on both sides
4x^2-12x+4=0
undistribute 4 for ease
4(x^2-3x+1)=0
since 4 does not equal zero, and the only thing that will get it to zero is 0,
x^2-3x+1=0
use quadratic equation

if you hahve
ax^2+bx+c=0
x=
1x^2-3x+1=0
a=1
b=-3
c=1

x=
x=
x=
x= or

aprox
x=2.61803 or 0.381966
