Question

please help me
find the error in the statement ​

Answer 1

Answer:

(a-3)square is asquare -2ab+bsquare not asquare -9

Answer 2

$(a - 3) {}^{2} = {a}^{2} + {3}^{2} - 2 \times a \times 3$

$(a - 3) {}^{2} = {a}^{2} + {3}^{2} - 6 a$

$the \: correct \: statement \: is \: \\ a {}^{2} - {3}^{2} = {a}^{2} - 9$
