She didn't put the sign's in the proper place, it should be ( x + 3 ) ( x - 7 )
Step-by-step explanation:
( x - 3 ) ( x + 7 ) = x² + 7x - 3x - 21 = x² + 4x - 21
( x + 3 ) ( x - 7 ) = x² - 7x + 3x - 21 = x² - 4x - 21
9 x 72 = 9 x ? + 9 x 2
72 = 8 x 9 = 4 x 2 x 9
9 x 72 = 9 x 4 + 9 x 2
0.9/1000=0.0009
