The solutions for x squared-4=0 are 2 and -3 true or false?

False.


The solutions are 2 and -2The solutions for x squared-4=0 are 2 and -3 true or false?
False, they are plus 2 and minus 2.





X^2 = 4





or if you like


(x+2) (x-2) = 0The solutions for x squared-4=0 are 2 and -3 true or false?
The answer is +2, or -2


because you subtract four on both sides then take the square root


Or if your want to factor you get(x-2)(x+2) set them equal to zero and get +2 -2
False.





x虏 - 4 = 0


x虏 = 4


x = 卤鈭? = 卤2


x = -2, 2
x虏 - 4 = 0


+4 + 4


x虏 = 4


鈭? 鈭?br>

鈭歺虏 = 卤鈭?





x = 卤2





Hope it helps :D x
I'll take WHO CARES A FLYING **** ABOUT MATH ANYWAY for a 1000, Alex!
