Question 84353
Solve by using the quadratic formula.  x^2 = 7x – 11 
:
First put the equation in ax^2+bx+c=0 form.
{{{x^2-7x+11=7x-7x-11+11}}}
{{{x^2-7x+11=0}}}
a=1 b=-7 c=11
The quadratic formula is:  {{{x=(-b+-sqrt(b^2-4ac))/(2a)}}}
{{{x=(-(-7)+-sqrt((-7)^2-4(1)(11)))/(2(1))}}}
{{{x=(7+-sqrt(49-44))/2}}}
{{{x=(7+-sqrt(5))/2}}}
Happy Calculating!!!!
