{x}^{2}  - 4x - 9 = 29 \\  {x}^{2}  - 4x - 38 = 0 \\  \\ x12 =  \frac{ - b  \frac{ + }{ - } \sqrt{d} }{2}  \\ d =  {b}^{2}  - 4ac \\ d = 16 + 152 = 168 \\  \\ x1 =   \frac{4 -  \sqrt{168} }{2}  \\ x2 =  \frac{4 +  \sqrt{168} }{2}

15. The equation below defines z as a differentiable function of x and y. Find the value of dz/dy at the point (1, 1, 1).
MariettaO [177]

Isolate the term with z^2.

x^2 - 5y^2 + xyz^2 = y - 4 \implies xyz^2 = -x^2 + 5y^2 + y - 4

Differentiate both sides with respect to y.

\dfrac{\partial(xyz^2)}{\partial y} = \dfrac{\partial(-x^2 + 5y^2 + y - 4)}{\partial y}

By the product and chain rules,

xz^2 + 2xyz \dfrac{\partial z}{\partial y} = 10y + 1

Solve for the partial derivative, then evaluate at (x,y,z) = (1,1,1).

\dfrac{\partial z}{\partial y} = \dfrac{10y + 1 - xz^2}{2xyz}

\dfrac{\partial z}{\partial y} \bigg|_{x=1,y=1,z=1} = \dfrac{10 + 1 - 1}{2} = \boxed{5}
