Question
Simplify the expression
10x2−30x
Evaluate
(x−3)(x×10)
Remove the parentheses
(x−3)x×10
Use the commutative property to reorder the terms
(x−3)×10x
Multiply the terms
10x(x−3)
Apply the distributive property
10x×x−10x×3
Multiply the terms
10x2−10x×3
Solution
10x2−30x
Show Solution
Find the roots
x1=0,x2=3
Evaluate
(x−3)(x×10)
To find the roots of the expression,set the expression equal to 0
(x−3)(x×10)=0
Use the commutative property to reorder the terms
(x−3)×10x=0
Multiply the terms
10x(x−3)=0
Elimination the left coefficient
x(x−3)=0
Separate the equation into 2 possible cases
x=0x−3=0
Solve the equation

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=0x=3
Solution
x1=0,x2=3
