What is the form of the Sum of Cubes identity?
O A. 8° +6° = (2-6) (e? + ab + 8)
O B. 2° -- (+ b) (4+ + ab + 8)
O c. 8° += (a + b) (82 - 25+ b}}
O D. 2° - 6° - (-6)( a + ab +62)

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
