Evaluate the expression at specific values of their variables. Evaluate
j^2 - 3k + j, when j = 6 and k = 10.
To evaluate the expression j^2 - 3k + j, when j = 6 and k = 10, we substitute these values into the expression and perform the calculations.
First, substitute j = 6 and k = 10 into the expression:
(6)^2 - 3(10) + 6
Next, we simplify the expression using the order of operations (PEMDAS/BODMAS):
36 - 30 + 6
Now, perform the addition and subtraction:
6 + 6
Finally, perform the addition:
12
Therefore, when j = 6 and k = 10, the expression j^2 - 3k + j equals 12.
