Question
Simplify the expression
44l4−1
Evaluate
l4×44−1
Solution
44l4−1
Show Solution

Find the roots
l1=−444443,l2=444443
Alternative Form
l1≈−0.388273,l2≈0.388273
Evaluate
l4×44−1
To find the roots of the expression,set the expression equal to 0
l4×44−1=0
Use the commutative property to reorder the terms
44l4−1=0
Move the constant to the right-hand side and change its sign
44l4=0+1
Removing 0 doesn't change the value,so remove it from the expression
44l4=1
Divide both sides
4444l4=441
Divide the numbers
l4=441
Take the root of both sides of the equation and remember to use both positive and negative roots
l=±4441
