No, unless "a" happens to be equal to 0, or to 1.
Is a squared plus b squared the same as a plus b squared?
No. If you expand (a + b)2 you get a2 + 2ab + b2. This is not equal to a2 + b2
What is negative sixty-four minus four squared?
Negative sixty-four minus four squared is equal to -80.
What is -1 squared equal to and why?
