Simplify the expression
1800x2−18000x
Evaluate
120(x×15)(x−10)
Remove the parentheses
120x×15(x−10)
Multiply the terms
1800x(x−10)
Apply the distributive property
1800x×x−1800x×10
Multiply the terms
1800x2−1800x×10
Solution
1800x2−18000x

Find the roots
x1=0,x2=10
Evaluate
120(x×15)(x−10)
To find the roots of the expression,set the expression equal to 0
120(x×15)(x−10)=0
Use the commutative property to reorder the terms
120×15x(x−10)=0
Multiply the terms
1800x(x−10)=0
Elimination the left coefficient
x(x−10)=0
Separate the equation into 2 possible cases
x=0x−10=0
Solve the equation

Evaluate
x−10=0
Move the constant to the right-hand side and change its sign
x=0+10
Removing 0 doesn't change the value,so remove it from the expression
x=10
x=0x=10
Solution
x1=0,x2=10
