Question Factor the expression 3(m−4) Evaluate 3m−12Solution 3(m−4) Show Solution Find the roots m=4 Evaluate 3m−12To find the roots of the expression,set the expression equal to 0 3m−12=0Move the constant to the right-hand side and change its sign 3m=0+12Removing 0 doesn't change the value,so remove it from the expression 3m=12Divide both sides 33m=312Divide the numbers m=312Solution More Steps Evaluate 312Reduce the numbers 14Calculate 4 m=4 Show Solution
