Answer:
-21
Step-by-step explanation:
Given:
Evaluate each expression if a = 2, b = -3, and c=4.
b ²- ( c² -a²)
Solve:
Since, it given that;
b²-(c²-a²) and a = 2, b = -3 , c = 4.
Therefore, we can substitute to find the answer.
-3² - ( 4² - 2²)
Following the PEMDAS:
-3² - ( 4² - 2²)
= -3² -12
= -9 - 12
= -21
Hence, the answer is - 21.
