QuestionEvaluate the expression $-x^{2}-2$ for $x=-6$ . What is the result?

Studdy Solution

STEP 1

Assumptions1. The variable x is given the value -6. The algebraic expression is $-x^{}-$

STEP 2

We substitute the given value of x into the algebraic expression.
$-(-6)^{2}-2$

STEP 3

We first need to calculate the square of -6.
$(-6)^{2} =36$

STEP 4

Now, substitute the value of $(-6)^{2}$ back into the expression.
$-36-2$

STEP 5

Finally, we perform the subtraction operation.
$-36-2 = -38$ So, for $x=-, -x^{2}-2=-38$ .

QuestionEvaluate the expression −x2−2-x^{2}-2−x2−2 for x=−6x=-6x=−6. What is the result?

Studdy Solution

STEP 1

Assumptions1. The variable x is given the value -6. The algebraic expression is −x−-x^{}-−x−

STEP 2

We substitute the given value of x into the algebraic expression.−(−6)2−2-(-6)^{2}-2−(−6)2−2

STEP 3

We first need to calculate the square of -6.(−6)2=36(-6)^{2} =36(−6)2=36

STEP 4

Now, substitute the value of (−6)2(-6)^{2}(−6)2 back into the expression.−36−2-36-2−36−2

STEP 5

Finally, we perform the subtraction operation.−36−2=−38-36-2 = -38−36−2=−38So, for x=−,−x2−2=−38x=-, -x^{2}-2=-38x=−,−x2−2=−38.
