Find the roots
f=1
Evaluate
(f−9)−(−7f−1)
To find the roots of the expression,set the expression equal to 0
(f−9)−(−7f−1)=0
Remove the parentheses
f−9−(−7f−1)=0

Add the numbers
8f−8
8f−8=0
Move the constant to the right-hand side and change its sign
8f=0+8
Removing 0 doesn't change the value,so remove it from the expression
8f=8
Divide both sides
88f=88
Divide the numbers
f=88
