Rajeev Malhotra 7 years, 11 months ago

let the three numbers are x, x+1 and x+2.

so (x)²+(x+1)²+(x+2)² = 77

x²+x²+2x+1+x²+4x+4= 77

3x²+6x+5 = 77

3x²+6x -72 =0

3x²+18x-12x-72 =0

3x(x+6)-12(x+6)=0

(3x-12)(x+6)=0

3x-12=0 or x+6 =0

3x=12 or x= -6

x=12/3=4 nor x=-6

x =4 , x=-6 is not possible because a natural number can not be negative.

so numbers are 4,5 and 6.
