Step by Step Solution
Step 1 :
Trying to factor by splitting the middle term
1.1 Factoring x2-9x-22
The first term is, x2 its coefficient is 1 .
The middle term is, -9x its coefficient is -9 .
The last term, "the constant", is -22
Step-1 : Multiply the coefficient of the first term by the constant 1 • -22 = -22
Step-2 : Find two factors of -22 whose sum equals the coefficient of the middle term, which is -9 .
-22 | + | 1 | = | -21 | ||
-11 | + | 2 | = | -9 | That's it |
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -11 and 2
x2 - 11x + 2x - 22
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-11)
Add up the last 2 terms, pulling out common factors :
2 • (x-11)
Step-5 : Add up the four terms of step 4 :
(x+2) • (x-11)
Which is the desired factorization
Final result :
(x + 2) • (x - 11)
