Which expression is equivalent to 27 + 15

Remark

3 is a common factor. If you pull 3 out using the distributive property, you get 3(9 + 5)

You could do this with much more complex questions like 625 + 730

For the question you were given, You could factor this into their primes.

15:  3 * 5

27: 3 * 3 * 3

The highest common factor is 3

So that is what comes out. The rest is inside the brackets.

3(5 + 9) shows what is left over.

For the example I used

625: 5 * 5 * 5 * 5

740: 5 * 2 * 2 * 37 There is only 5 that is common to both of these.

5(125 + 148)

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0
