Question

obtain zeros of given p(x) (1) p(x) = x²-5x-54​

Answer 1

Answer:

Step-by-step explanation:

Factoring  x2-5x-54  

The first term is,  x2  its coefficient is  1 .

The middle term is,  -5x  its coefficient is  -5 .

The last term, "the constant", is  -54  

Step-1 : Multiply the coefficient of the first term by the constant   1 • -54 = -54  

Step-2 : Find two factors of  -54  whose sum equals the coefficient of the middle term, which is   -5 .

     -54    +    1    =    -53  

     -27    +    2    =    -25  

     -18    +    3    =    -15  

     -9    +    6    =    -3  

     -6    +    9    =    3  

     -3    +    18    =    15  

     -2    +    27    =    25  

     -1    +    54    =    53

x2 - 5x - 54  = 0
