Both (x - 3)(x + 3) and (3 – x)(3+ x) contain a sum and a difference and have only 3 and x in each factor.
If each expression is rewritten in standard form, will the two expressions be the same?
Explain or show your reasoning.

Clara solved the equation 7/3x = −2/3 as shown → 7/3x( 3/7 ) = −2/3 ( 3/7 ) x = −14 what is clara’s error?
