Question

2y - (x + 1)² when x = -4 and y = 9simplify the following

Answer 1

We are given the following expression

`2y-(x+1)^2`

Where the values of x and y are also given as

`x=-4\: and\: y=9`

It would be much easier if we first substitute the values of x and y then simplify the expression

`2(9)-(-4+1)^2`

Now let's simplify the expression

`\begin{gathered} 2(9)-(-4+1)^2 \\ 18-(-3)^2 \\ 18-(6) \\ 18-6 \\ 12 \end{gathered}`

Therefore, the given expression is simplified to 12

`\begin{gathered} 2y-(x+1)^2=12 \\ when\: \: x=-4\: and\: y=9 \end{gathered}`
