5. Given
[tex]a^2-bw[/tex]
You know that:
a=-1
b=2
w=-10
Replace these values into the expression:
[tex](-1)^2-2\cdot(-10)[/tex]
Following the order of operations, first, you have to solve the exponent and the multiplication:
[tex]1-(-20)[/tex]
Both minus signs form a "double negative" when this happens, the signs cancel each other and turn into a plus sign, so that:
[tex]1+20[/tex]
Next, solve the addition
[tex]1+20=21[/tex]
The result of this operation is 21.
