If X is the length of the side of the
square, and 1 is the width of the bar, these tiles represent (X + 3) (X + 2)
= X2 + 5X + 6. What is X if X2 + 5X + 6 = 42?
What
other values of the equation, besides 42, will give a whole number value for
X?
What other values of the equation will give a negative number value for
X?
