Answer 2

Answer:

$(55)^{2} = 3025.$

Step-by-step explanation:

Start off with the nearest perfect square or a number whose square you don't have to calculate.  You can also use 10 or 100, depending on your question (eg. 98 squared, or 15.6 squared).

Identity:   $(A - B)^{2} = A^{2} +B^{2}+2AB$

$(55)^{2} = (50 + 5)^{2}$

$(50+5)^{2} = (50)^{2} + (5)^{2} + 2(50)(5)$

$(50+5)^{2} [tex]= 2500 + 25 + 500</p><p>(50 + 55)^{2} = 3025$

$(55)^{2} = 3025.$
