Question

8x^2+73x + 9 solve the sum ​

Answer 1

Answer:

(x-9)•(8x-1)

Step-by-step explanation:

The first term is, 8x2 its coefficient is 8 .

The middle term is, -73x its coefficient is -73 .

The last term, "the constant", is +9

Step-1 : Multiply the coefficient of the first term by the constant 8 • 9 = 72

Step-2 : Find two factors of 72 whose sum equals the coefficient of the middle term, which is -73 .

-72 + -1 = -73 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -72 and -1

8x2 - 72x - 1x - 9

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

8x • (x-9)

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

1 • (x-9)

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

(8x-1) • (x-9)

Which is the desired factorization

result = (x-9)•(8x-1)
