Simplify the expression
x2−8x+12
Evaluate
(x−2)(x−6)
Apply the distributive property
x×x−x×6−2x−(−2×6)
Multiply the terms
x2−x×6−2x−(−2×6)
Use the commutative property to reorder the terms
x2−6x−2x−(−2×6)
Multiply the numbers
x2−6x−2x−(−12)
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
x2−6x−2x+12

Find the roots
x1=2,x2=6
Evaluate
(x−2)(x−6)
To find the roots of the expression,set the expression equal to 0
(x−2)(x−6)=0
Separate the equation into 2 possible cases
x−2=0x−6=0
Solve the equation
More Steps
Evaluate
x−2=0
Move the constant to the right-hand side and change its sign
x=0+2
Removing 0 doesn't change the value,so remove it from the expression
x=2
x=2x−6=0
Solve the equation
More Steps
Evaluate
x−6=0
Move the constant to the right-hand side and change its sign
x=0+6
Removing 0 doesn't change the value,so remove it from the expression
x=6
x=2x=6
Solution
x1=2,x2=6
