Question
Simplify the expression
−24u2+72u
Evaluate
(−3u×8)(u−3)
Remove the parentheses
−3u×8(u−3)
Multiply the terms
−24u(u−3)
Apply the distributive property
−24u×u−(−24u×3)
Multiply the terms
−24u2−(−24u×3)
Multiply the numbers
−24u2−(−72u)
Solution
−24u2+72u
Show Solution

Find the roots
u1=0,u2=3
Evaluate
(−3u×8)(u−3)
To find the roots of the expression,set the expression equal to 0
(−3u×8)(u−3)=0
Multiply the terms
(−24u)(u−3)=0
Remove the parentheses
−24u(u−3)=0
Change the sign
24u(u−3)=0
Elimination the left coefficient
u(u−3)=0
Separate the equation into 2 possible cases
u=0u−3=0
Solve the equation
More Steps

Evaluate
u−3=0
Move the constant to the right-hand side and change its sign
u=0+3
Removing 0 doesn't change the value,so remove it from the expression
u=3
u=0u=3
Solution
u1=0,u2=3
