it ought to help in case you ought to write * for "situations". it is otherwise confusing to make certain the answer. perchance i do not realize...oh nicely, ask your instructor! a million. x = 4/3? 2. x= -sixty 4/3 3. x= 25/4 ...

-x^2 + 4 = 0
-x^2 = -4
x^2 = -4/-1
x^2 = 4
x = ±√4
x = ±2
-x^2 = -4
x^2 = -4/-1
x^2 = 4
x = ±√4
x = ±2

4 = x^2
sqrt 4 = x
x = -2 or 2
sqrt 4 = x
x = -2 or 2

-x^2+4=0
-x^2=-4
x^2=4
x=sqrt4
x=+ or - 2and this is the answer
-x^2=-4
x^2=4
x=sqrt4
x=+ or - 2and this is the answer

0=4-x^2=>
0=(2+x)(2-x)=>
x=2 or -2
0=(2+x)(2-x)=>
x=2 or -2
