Question Simplify the expression 9x2−36x+36 Evaluate (3x−6)2Use (a−b)2=a2−2ab+b2 to expand the expression (3x)2−2×3x×6+62Solution 9x2−36x+36 Show Solution Factor the expression 9(x−2)2 Evaluate (3x−6)2Evaluate 9x2−36x+36Solution 9(x−2)2 Show Solution Find the roots x=2 Evaluate (3x−6)2To find the roots of the expression,set the expression equal to 0 (3x−6)2=0The only way a power can be 0 is when the base equals 0 3x−6=0Move the constant to the right-hand side and change its sign 3x=0+6Removing 0 doesn't change the value,so remove it from the expression 3x=6Divide both sides 33x=36Divide the numbers x=36Solution More Steps Evaluate 36Reduce the numbers 12Calculate 2 x=2 Show Solution
