Question

What is x^2-11x-5=0

Solve in a quadratic formula, and the answer has to have the use of integers or fractions. No DECIMALS. I need this fast!!!

Answer 1

`x^2-11x-5=0\\a=1,b=-11,c=-5\\D=b^2-4ac=(-11)^2-4*1*(-5)=121+20=141\\x_(1,2)=(-b\pm√(D) )/(2a) \\x_1=(11+√(141) )/(2) \\x_2=(11-√(141) )/(2)`
