HELP! <img src="https://tex.z-dn.net/?f=%5Csqrt%7Bx-1%7D-x%3D-7" id="TexFormula1" title="\sqrt{x-1}-x=-7" alt="\sqrt{x-1}-x=

$\huge \huge \huge\huge\mathrm{ \boxed{ \boxed{ \boxed{ \boxed{ \boxed {\boxed{ \huge\mathfrak{ Solution}}}}}}}}$

$\sqrt{x - 1} - x = - 7$

$\sqrt{x - 1} =x - 7$

$x - 1 = (x - 7) {}^{2}$

$x - 1 = {x}^{2} + 49 - 14x$

${x}^{2} - 14x + 49 - x + 1 = 0$

${x}^{2} - 15x + 50 = 0$

${x}^{2} - 10x - 5x + 50 = 0$

$x(x - 10) - 5(x - 10) = 0$

$(x - 5)(x - 10) = 0$

$x = 5 \: \: \: or \: \: \: x = 10$

It is equal to 2(x)^3 because pemdas, exponnets come before multiplication so it would be x^3 then multiply whatever that is by 2

2x^3 is answer (4th choice)
