Simplify the expression
8x2−64x
Evaluate
(x−8)(x×8)
Remove the parentheses
(x−8)x×8
Use the commutative property to reorder the terms
(x−8)×8x
Multiply the terms
8x(x−8)
Apply the distributive property
8x×x−8x×8
Multiply the terms
8x2−8x×8
Solution
8x2−64x
Show Solution
Find the roots
x1=0,x2=8
Evaluate
(x−8)(x×8)
To find the roots of the expression,set the expression equal to 0
(x−8)(x×8)=0
Use the commutative property to reorder the terms
(x−8)×8x=0
Multiply the terms
8x(x−8)=0
Elimination the left coefficient
x(x−8)=0
Separate the equation into 2 possible cases
x=0x−8=0
Solve the equation
More Steps
Evaluate
x−8=0
Move the constant to the right-hand side and change its sign
x=0+8
Removing 0 doesn't change the value,so remove it from the expression
x=8
x=0x=8
Solution
x1=0,x2=8
