Evaluate the algebraic expression for the given values of the variables. \[ x^{2}-8(x-y), \text { for } x=8 \text { and } y=4 \] When $x=8$ and $y=4, x^{2}-8(x-y)=$

Step 1 ：Given the algebraic expression \(x^{2}-8(x-y)\), where \(x=8\) and \(y=4\)

Step 2 ：Substitute the given values of x and y into the expression, which gives \(8^{2}-8(8-4)\)

Step 3 ：Simplify the expression to get \(64-8*4\)

Step 4 ：Further simplify to get \(64-32\)

Step 5 ：Finally, we get the result as \(32\)
