Evaluate
1−x2
Rewrite the expression in exponential form
12−x2
Use a2−b2=(a−b)(a+b) to factor the expression

Find the roots
x1=−1,x2=0,x3=1
Evaluate
24x2−24x6
To find the roots of the expression,set the expression equal to 0
24x2−24x6=0
Factor the expression
24x2(1−x4)=0
Divide both sides
x2(1−x4)=0
Separate the equation into 2 possible cases
x2=01−x4=0
The only way a power can be 0 is when the base equals 0
x=01−x4=0
Solve the equation
More Steps
Evaluate
1−x4=0
Move the constant to the right-hand side and change its sign
−x4=0−1
Removing 0 doesn't change the value,so remove it from the expression
−x4=−1
Change the signs on both sides of the equation
x4=1
Take the root of both sides of the equation and remember to use both positive and negative roots
x=±41
Simplify the expression
x=±1
Separate the equation into 2 possible cases
x=1x=−1
x=0x=1x=−1
Solution
x1=−1,x2=0,x3=1
