Question Simplify the expression Solution 16x2−8x+1 Evaluate (4x−1)2Use (a−b)2=a2−2ab+b2 to expand the expression (4x)2−2×4x×1+12Solution 16x2−8x+1 Show Solution Find the roots Find the roots of the algebra expression x=41Alternative Form x=0.25 Evaluate (4x−1)2To find the roots of the expression,set the expression equal to 0 (4x−1)2=0The only way a power can be 0 is when the base equals 0 4x−1=0Move the constant to the right-hand side and change its sign 4x=0+1Removing 0 doesn't change the value,so remove it from the expression 4x=1Divide both sides 44x=41Solution x=41Alternative Form x=0.25 Show Solution
