Question

Which equation is related to sqrt(x+10)-1 =x

Answer 1

x + 10 = x² + 2x + 1

Explanation:

`√(x + 10)` - 1 = x

x + 1 =
`√(x + 10)`

Squaring both sides gives;

(x + 1)² = (
`√(x + 10)`)²

x + 10 = x² + 2x + 1

Answer 2

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.
