Use the commutative property to reorder the terms
324l2−4−1
Solution
324l2−5
Show Solution
Find the roots
l1=−185,l2=185
Alternative Form
l1≈−0.124226,l2≈0.124226
Evaluate
l2×324−4−1
To find the roots of the expression,set the expression equal to 0
l2×324−4−1=0
Use the commutative property to reorder the terms
324l2−4−1=0
Subtract the numbers
324l2−5=0
Move the constant to the right-hand side and change its sign
324l2=0+5
Removing 0 doesn't change the value,so remove it from the expression
324l2=5
Divide both sides
324324l2=3245
Divide the numbers
l2=3245
Take the root of both sides of the equation and remember to use both positive and negative roots
l=±3245
