−9f−4+4f+2
Add the terms
More Steps
Evaluate
−9f+4f
Collect like terms by calculating the sum or difference of their coefficients
(−9+4)f
Add the numbers
−5f
−5f−4+2
Solution
−5f−2
Show Solution
Find the roots
f=−52
Alternative Form
f=−0.4
Evaluate
(−9f−4)−(−4f−2)
To find the roots of the expression,set the expression equal to 0
(−9f−4)−(−4f−2)=0
Remove the parentheses
−9f−4−(−4f−2)=0

−5f
−5f−4+2
Add the numbers
−5f−2
−5f−2=0
Move the constant to the right-hand side and change its sign
−5f=0+2
Removing 0 doesn't change the value,so remove it from the expression
−5f=2
Change the signs on both sides of the equation
5f=−2
Divide both sides
55f=5−2
Divide the numbers
f=5−2
Solution
f=−52
