Question

analyze the product

(a-3)(a-2)-56/(55)²
do it fast​

Answer 1

Answer:

Put a-2 = x then a-3 = x-1

The given equation can be written as x(x-1) = 56/(55x55)

x^2 -x = (55+1)/(55x55) = 1/55 + 1/55^2

x^2 - 1/55^2 - x - 1/55 = 0

(x + 1/55)(x- 1/55) - 1 (x+ 1/55) = 0

(x+1/55)(x - 1/55 -1) = 0

(x + 1/55)(x- 56/55) = 0

x = -1/55 or x = 56/55

i.e., a -2 = -1/55 or a-2 = 56/55

a = 109/55 or a= 166/55
