Answer:
25
Step-by-step explanation:
In this it's going to be pretty simple.
[tex]b^{2}[/tex] is going to be -3 * -3 = 9
When you have a square you multiply the number by itself.
So
9 - 4 * 1 * -4
here you have to remember order of operations.
Please - Parens
Excuse - Exponents
My - Multiplication
Dear - Division
Aunt - Addition
Sally - Subtraction.
Multiplication and Division are done at the same time left to right
Addition and Subtraction are done at the same time left to right.
So
9 - 4 * 1 * -4
You do the multiplication first.
4*1 = 4
4 * -4 = -16
Now you have
9 - - 16
This turns into
9 + 16
your answer is 25.
