The sum of the squares of a and B is the square of a + the square of B, right?

No, the square of (a + b) is equal to a + 2Ab + B, not equal to a + B

A + B = 4. A square + b square = 4 find the sum of a square and b square (a-b) ^ 2
emergency

According to the meaning of the title, a + B = 4, a square + b square = 4,
Then the square of (a + b) = 16 can be expanded to obtain 2Ab = 12ab = 6, and the square of both sides can obtain a square and b square = 36
Square of (a-b) = - 8
Square of (a-b) = - 10

Is square the same as square meter?
