Question

What polynomial identity should be used to prove that 133 = 125 + 8?
Difference of Cubes
Difference of Squares
Square of Binomial
Sum of Cubes

Answer 1

In general,
\(a^3+b^3=(a+b)(a^2-ab+b^2)\)
\(a^3-b^3=(a-b)(a^2+ab+b^2)\)
Specifically for this case,
\(125=5^3; 8=2^3; so 125+8=5^3+2^3=...\)

Answer 2

im thinking it's difference of cubes

Answer 3

you still there

Answer 4

hint:
sum is the result of addition
difference is the result of subtraction.
