Question

factorise x-64..................​

Answer 1

Answer:

$x - 64 = \\ x = {8}^{2}$

Answer 2

Answer:

x2 - 8x - 64 = 8

   

Step-by-step explanation:

Factoring  x2 - 8x - 64

The first term is,  x2  its coefficient is  1 .

The middle term is,  -8x  its coefficient is  -8 .

The last term, "the constant", is  -64

Step-1 : Multiply the coefficient of the first term by the constant   1 • -64 = -64

Step-2 : Find two factors of  -64  whose sum equals the coefficient of the middle term, which is   -8 .

     -64    +   1    =    -63

     -32    +   2    =    -30

     -16    +   4    =    -12

     -8    +   8    =    0

     -4    +   16    =    12

     -2    +   32    =    30

     -1    +   64    =    63
