Step-by-step explanation:
Assumption: Let the consecutive positive integers be x and (x+1).
According to the question,
x² + (x+1)² = 365
Or, x² + (x² + 1 + 2x) = 365
Or, 2x² + 2x + 1 = 365
Or, 2x²+2x+1-365=0
Or, 2x²+2x-364=0
Or, 2(x²+x-182)=0
Or, x²+x-182= 0/2
Or, x²+x-182 =0
Or, x²+14x-13x-182=0
Or, x(x+14)-13(x+14)=0
Or, (x+14)(x-13)=0
Or, x-13=0/(x+14)
Or, x-13=0
Or, x=13
Therefore the consecutive positive integers are 13(x) and 14 (x+1).
