Question

x² + (x + 1)² = 365 plz solve​

Answer 1

Answer:

x value is 13

Step-by-step explanation:

x^2+ x^2 + 1+ 2x =365

2x^2 + 2x + 1 = 365

2x^2+ 2x=365-1

2x^2+ 2x= 364

2x^2 + 2x - 364=0

(2x^2 + 2x - 364)/2 =0

x^2+ x- 182 =0

x^2+ 14 x -13 x -182 =0

x( x+14) - 13 ( x + 14) =0

(x-13 ) ( x +14 ) =0

x -13 =0, x = 13

x+14 =0, x = -14

consider positive value for x = 13
