Question Simplify the expression 9x2−180x Evaluate (x×9)(x−20)Remove the parentheses x×9(x−20)Use the commutative property to reorder the terms 9x(x−20)Apply the distributive property 9x×x−9x×20Multiply the terms 9x2−9x×20Solution 9x2−180x Show Solution Find the roots x1=0,x2=20 Evaluate (x×9)(x−20)To find the roots of the expression,set the expression equal to 0 (x×9)(x−20)=0Use the commutative property to reorder the terms 9x(x−20)=0Elimination the left coefficient x(x−20)=0Separate the equation into 2 possible cases x=0x−20=0Solve the equation More Steps Evaluate x−20=0Move the constant to the right-hand side and change its sign x=0+20Removing 0 doesn't change the value,so remove it from the expression x=20 x=0x=20Solution x1=0,x2=20 Show Solution
