What is smallest number avocados that can placed in basket wiith 50 and 75 pieces

125 pieces

Perhaps you want to factor these.

The first one cannot be factored as written. A different expression can be.
.. q^2 +11qt +18t^2 = (q^2 +9qt) +(2qt +18t^2) = q(q +9t) +2t(q +9t)
.. = (q +2t)*(q +9t)

x^2 -14xy -15y^2 = (x -15y)*(x +y) . . . . . . . -15 and 1 are factors of -15 that add to -14
