Does anyone know how to solve this, I need step by step on how to do this! Thank you!

Answer:
Step-by-step explanation:
=5
as a = -3 and the value is 14-a2 so 14-(-3)2
the same signs are allways positive but the we first have to solve brackets so -3x-3(its the square) the square would be 9 so 14-(9)
so 14-9 = 5 i hope it helpss

We have to find the value of 14 - a² [To Find]
We know that the value of a = -3 [Given]
We have to put the value of a = -3 in 14 - a²
