Question
Find the roots
x1=−42,x2=42
Alternative Form
x1≈−6.480741,x2≈6.480741
Evaluate
x2−42
To find the roots of the expression,set the expression equal to 0
x2−42=0
Move the constant to the right-hand side and change its sign
x2=0+42
Removing 0 doesn't change the value,so remove it from the expression
x2=42
Take the root of both sides of the equation and remember to use both positive and negative roots
x=±42
Separate the equation into 2 possible cases
x=42x=−42
Solution
x1=−42,x2=42
Alternative Form
x1≈−6.480741,x2≈6.480741
