Answer:
Factoring x2-15x-34
The first term is, x2 its coefficient is 1 .
The middle term is, -15x its coefficient is -15 .
The last term, "the constant", is -34
Step-1 : Multiply the coefficient of the first term by the constant 1 • -34 = -34
Step-2 : Find two factors of -34 whose sum equals the coefficient of the middle term, which is -15 .
-34 + 1 = -33
-17 + 2 = -15 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -17 and 2
x2 - 17x + 2x - 34
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-17)
Add up the last 2 terms, pulling out common factors :
2 • (x-17)
Step-5 : Add up the four terms of step 4 :
(x+2) • (x-17)
