What values of x make the equation x^2+4x−4=0 true? simplify any radicals

we can't factor so use quadratic formula

for

we have

a=1, b=4, c=-4

x=-2+2√2 and x=-2-2√2 are the values of x that satisfy the equation

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an

hope this !
