Question

h²+8h+20 ayudaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

Answer 1

Respuesta:

(h + 2) • (h - 10)

Explicación paso a paso:

1.1     Factoring  h2-8h-20 

The first term is,  h2  its coefficient is  1 .

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

The last term, "the constant", is  -20 

Step-1 : Multiply the coefficient of the first term by the constant   1 • -20 = -20 

Step-2 : Find two factors of  -20  whose sum equals the coefficient of the middle term, which is   -8 .

     -20   +   1   =   -19     -10   +   2   =   -8   That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -10  and  2 

                     h2 - 10h + 2h - 20

Step-4 : Add up the first 2 terms, pulling out like factors :

                    h • (h-10)

              Add up the last 2 terms, pulling out common factors :

                    2 • (h-10)

Step-5 : Add up the four terms of step 4 :

                    (h+2)  •  (h-10)

             Which is the desired factorization

Final result :

(h + 2) • (h - 10)
