We use the answer to get to the question.

# data[].attributes.custom_properties.HAn_rxh8
I will check by working backwards and see if I get back the same answer.

# data[].attributes.body
expand the awnser to see if we get back the same one

# data[].attributes.custom_properties.HAn_rxh8
I will check my work by substituting the unknown with a random number and compare it with both the initial equation given by the question and the final answer after you simplify it.

# data[].attributes.custom_properties.HAn_rxh8
I can use the A*2 - B*2 pattern to help me overcome the error

# data[].attributes.custom_properties.HAn_rxh8
Once obtaining the factorised expression, you can expand it to see if you can get the original expression.    

# data[].attributes.body
Expand your answer and see if it is the same as the original

# data[].attributes.custom_properties.HAn_rxh8
double check by working backwards, expand the answer

# data[].attributes.body
Strategy to reduce errors

# data[].attributes.custom_properties.HAn_rxh8
Expand your answer and ensure it is the same as the original

# data[].attributes.custom_properties.HAn_rxh8
Look more carefully and do not expand the expression.

# data[].attributes.body
Make sure to know that 81x^2 is not 81x*81x and is 9x*9x and remember to apply it to other stuff and not skip step

# data[].attributes.body
Replace the unknown with a whole number that is not zero and solve both the original and your answer. If they don't match, answer is wrong, if they match it is correct.

# data[].attributes.custom_properties.HAn_rxh8
substitute the numbers or a and b, then substitute back

# data[].attributes.custom_properties.HAn_rxh8
by doing the question again and checking if the answers obtsined sre the same

# data[].attributes.body
work backwards using the formulas provided to see if you get the same answer

# data[].attributes.custom_properties.HAn_rxh8
change the unknown variable to a number that is not 0. If the answer does not match, your answer is problaby wrong
