Answer:

x + 10 = x² + 2x + 1

Explanation:


√(x + 10) - 1 = x

x + 1 =
√(x + 10)

Squaring both sides gives;

(x + 1)² = (
√(x + 10)

x + 10 = x² + 2x + 1

Answer:

option B

Explanation:

the given equation is,


√(x+10)-1 =x.................................(1)

adding both side by 1 in equation (1)


√(x+10)= x + 1

squaring both side

x + 10 = ( x + 1 )²

we know,

( a + b )² = a² + b² + 2 a b

x + 10 = x² + 2 x + 1

hence, the correct answer is option B.
