Question Simplify the expression 9−24m+16m2 Evaluate (3−4m)2Use (a−b)2=a2−2ab+b2 to expand the expression 32−2×3×4m+(4m)2Solution 9−24m+16m2 Show Solution Find the roots m=43Alternative Form m=0.75 Evaluate (3−4m)2To find the roots of the expression,set the expression equal to 0 (3−4m)2=0The only way a power can be 0 is when the base equals 0 3−4m=0Move the constant to the right-hand side and change its sign −4m=0−3Removing 0 doesn't change the value,so remove it from the expression −4m=−3Change the signs on both sides of the equation 4m=3Divide both sides 44m=43Solution m=43Alternative Form m=0.75 Show Solution
