Question

Please help! How can I solve this equation? Reminder: x = -2, y = -3, z = 5.

Answer 1

Given expression is

`(-z^2(1-2x))/(y-x)`

Given

`x=-2,y=-3,z=5`

Substituting in the given expression,

`\begin{gathered} (-z^2(1-2x))/(y-x)=(-(5)^2(1-2(-2)))/(-3-(-2)) \\ =(-25(1+4))/(-1) \\ =125 \end{gathered}`

Hence, the value of the given expression is 125.
