I wanna Grad on time. Remember this formula Example ; x^3 + 1/8 = (x)^3 + (1/2)^3 = (x+1/2)(x^2 +1/4 -x/2) 27 x^3 + 1 = (3x)^3 + (1)^3 = (3x+1)(9x^2 + 1 - 3x)
These are all sums or differences of cubes: . . . . . . . . . . . . . . . To learn how to do the factorizations, try studying a lesson on special factoring formulas. Then memorize the two "cubes" formulas!!
Hey, Thanks... Does that work with both? Can you give me a Example how Number 7 work with that?
