Question
Simplify the expression
143l4−1
Evaluate
l4×143−1
Solution
143l4−1
Show Solution

Find the roots
l1=−14341433,l2=14341433
Alternative Form
l1≈−0.289178,l2≈0.289178
Evaluate
l4×143−1
To find the roots of the expression,set the expression equal to 0
l4×143−1=0
Use the commutative property to reorder the terms
143l4−1=0
Move the constant to the right-hand side and change its sign
143l4=0+1
Removing 0 doesn't change the value,so remove it from the expression
143l4=1
Divide both sides
143143l4=1431
Divide the numbers
l4=1431
Take the root of both sides of the equation and remember to use both positive and negative roots
l=±41431
