Question

Solve the quadratic equation by using either a numeric or a graphic approach.
x^2-11x-121= 0

Answer 1

Answer:

x= 11/2 + 11/2√5 or x= 11/2 + −11/2√5

Step-by-step explanation:

For this equation: a=1, b=-11, c=-121

1x^2−11x−121=0

Step 1: Use quadratic formula with a=1, b= -11, c= -121.

x= (−b±√b^2−4ac)/2a

x= (−(−11)±√(−11)2−4(1)(−121))/2(1)

x= (11±√605)/2

x=11/2 + 11/2√5 or x=11/2 −11/2√5
