Find the solutions to the following quadratic equation using the quadratic formula: x^2 - 12x + 36 = 0 Write the answers as integers.
Yeah so do you know the quadratic formula?
@Keridavis
x+x-12x+36=0
then.. um.. i forgot what was next..
Here u go .. just use this formula.,, http://www.oncalc.com/wp-content/uploads/2011/02/quadratic-equation-calculator.gif
so we know it is a quadratic because it is in this form, a^2+a+5
so what a b and c? though/
sorry I'm confusing you, lets start over
I'm so lost!
using x^2 - 12x + 36 = 0 ax2 + bx + c like so. Now use the quadratic formula
\[\large ax^2+bc+c=0\\ x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\] it is a direct computation
\[x^2 - 12x + 36 = 0 \\a=1,b=-12,c=36\]
course it would be a lot easier to recognize \[x^2-12x+36=(x-6)^2\]and then set \[(x-6)^2=0\\ x-6=0\\x=6\]
you will get \(x=6\) if you use the formula was well
Thank you hun.
