You can put this solution on YOUR website! Directions: determine whether each of the following trinomials is a perfect square. If it is, factor the trinomial.
#48
x^2-24x+48
Not a perfect square because 48 is not a perfect square and the
middle term is not twice the product of the square roots of the 1st and 3rd
terms.
#54
16x^2+40xy+25y^2
It is a perfect square:
(4x+5y)^2
