what i the value of 14-a2 given a=-3
Do you mean
14 - 2 a^2 ?????
a^2 is a squared or a times a
if so then
14 - (-3)(-3) = 14 - 9
which is around 5
14 - a^2 = 14 - (-3)^2 = 14-9 = 5.
14- a2 a=3
To find the value of 14-a^2 given a = -3, we first substitute -3 into the equation. Then, we square -3 (a^2 = (-3)^2 = 9). Finally, we subtract the result from 14 to get the value:
14 - a^2 = 14 - 9 = 5
So, the value of 14-a^2, given that a = -3, is 5.
