what is the value of 14-a^2 given a=-3
( - 3 )² = 9 so:
14 - ( - 3 )² = 14 - 9 = 5
To find the value of 14 - a^2 when a = -3, we substitute the value of a into the expression.
First, we need to substitute a = -3 into the expression:
14 - (-3)^2
Now, we simplify the expression:
14 - (-3)^2 = 14 - 9
Finally, we solve the expression:
14 - 9 = 5
Therefore, the value of 14 - a^2 when a = -3 is 5.
