Determine whether each of the following is a trinomial square.
Conditions: 1st and 3rd terms are perfect squares
2nd term is + or - twice the product of the square roots of 1st and 3rd
1. x^2-14x + 49 -------yes
2. x^2-10x - 25 -------yes
3. 36x^2-24x+16 -------no; middle term is not 2(6x)(4)=48x
4. 16x^2-40xy+25y^2 -----yes
5. 9x^2 - 36x + 24 ------no; 24 is not a perfect square
