Answer:
-147
Step-by-step explanation:
We can solve this by plugging in p = 5 and q=−2 and then evaluating using PEMDAS which tells us the order we do the math in by operation
Remember,
PEMDAS means
Parenthesis
Exponents
Multiplication and Division ( perform going left to right )
Addition and Subtraction ( perform going left to right )
-3(p-q)²
==> plug in p = 5 and q = -2
-3(5-(-2))²
==> remove parenthesis on -2
-3(5 + 2)²
==> do the operations inside of the parenthesis
-3(7)²
==> do the exponents
-3(49)
==> multiply -3 and 49
=-147
