Question

What is the solution of square root x^2 + 49=x+5

Answer 1

x = 12/5

Explanation:

`\sqrt{x^(2)+49 } = x +5`

Square both sides: (
`\sqrt{x^(2) +49}`)
`^(2)` = (x+5)
`^(2)`

`x^(2) + 49 = (x+5)(x+5)\\`

`x^(2) +49` =
`x^(2) + 10x + 25\\`

49 = 10x + 25

24 = 10x

`(12)/(5)` = x

Answer 2

-44

Explanation:

√x²+49=x+5

X+49=x+5

x-x=5-49

=-44
