Because the 2 minuses make a plus so -3 x -3 = 9
The equation 3 by 3 is 9. This is a math equation.
9
I am trying to read this right: (9 x 5) - x3 = ? or 9 x (5 - x3) = ? Which one is it?
(x - 3)(x2 + 3x + 3)
x3 + 9x2 + 27x + 27 Given the numbers in the equation, we can likely bet on (x + 3) being a factor. Let's try it with artificial division: 3 * 1 = 3 9 - 3 = 6 3 * 6 = 18 27 - 18 = 9 3 * 9 = 27 27 - 27 = 0 Bingo. So let's carry it out in long division:                       x2 + 6x + 9                    _____________________ x + 3 ) x3 + 9x2 + 27x + 27                        x3 + 3x2                                        6x2 + 27x                                        6x2 + 18x                                                                9x + 27                                                                9x + 27                                                                                    0 So we have: x3 + 9x2 + 27x + 27 = (x + 3)(x2 + 6x + 9) Which we can now factor further with relative ease: = (x + 3)(x + 3)(x + 3) = (x + 3)3

It is 3/4 x3/2 since dividing is the same as multiplying by the reciprocal. and this is 9/8 or 1 and 1/8
3 squared is equal to 9

In the case of a binomial in general, the only way you can factor it is by looking for common factors in each term. In other words, check whether there is a common factor (in this case) in "6x" and in "27". If there is, take this factor out.
