Evaluate the expression at specific values of their variables.
Evaluate j2 − 3k + j, when j = 6 and k = 10.
To evaluate the expression j2 − 3k + j when j = 6 and k = 10, we substitute these values of j and k into the expression.
Replacing j with 6 and k with 10, we get:
(6)2 - 3(10) + 6
Simplifying the expression inside the parentheses first, we have:
36 - 3(10) + 6
Multiplying 3 by 10, we get:
36 - 30 + 6
Next, subtracting 30 from 36, we get:
6 + 6
Finally, adding 6 and 6, we get:
12
Therefore, when j = 6 and k = 10, the expression j2 − 3k + j equals 12.
