Evaluate the variable expression when -= 6, b= 5, and c= -3

34

Step-by-step explanation:

Order of Operations: BPEMDAS

Step 1: Write out equation

(b - 2a)² + bc

Step 2: Define variables

a = 6

b = 5

c = 3

Step 3: Plug in

(5 - 2(6))² + 5(-3)

Step 4: Multiply

(5 - 12)² - 15

Step 5: Parenthesis

(-7)² - 15

Step 6: Exponents

49 - 15

Step 7: Subtract
