Solve the equation 6x^2-24=0
8x2-128=0 it is a algebra 1 question it says to solve the equation
 
8x2 -128 = 0
 
8x2 = 128         [Add 128 to both sides of the equation]
 
x2 = 16             [Divide both sides by 8]
 
√x2 = √16        [Take the square root of both sides]
 
x = ±4
 
-----------
 
6x2 - 24 = 0
 
6x2 = 24           [Add 24 to both sides]
 
x2 = 4              [Divide both sides by 6]
