Simplify the expression
x2−5x+6
Evaluate
(x−3)(x−2)
Apply the distributive property
x×x−x×2−3x−(−3×2)
Multiply the terms
x2−x×2−3x−(−3×2)
Use the commutative property to reorder the terms
x2−2x−3x−(−3×2)
Multiply the numbers
x2−2x−3x−(−6)
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
x2−2x−3x+6

Find the roots
x1=2,x2=3
Evaluate
(x−3)(x−2)
To find the roots of the expression,set the expression equal to 0
(x−3)(x−2)=0
Separate the equation into 2 possible cases
x−3=0x−2=0
Solve the equation
More Steps
Evaluate
x−3=0
Move the constant to the right-hand side and change its sign
x=0+3
Removing 0 doesn't change the value,so remove it from the expression
x=3
x=3x−2=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=3x=2
Solution
x1=2,x2=3
