Step by Step Solution
Step 1 :
Trying to factor by splitting the middle term
1.1 Factoring x2+14x+33
The first term is, x2 its coefficient is 1 .
The middle term is, +14x its coefficient is 14 .
The last term, "the constant", is +33
Step-1 : Multiply the coefficient of the first term by the constant 1 • 33 = 33
Step-2 : Find two factors of 33 whose sum equals the coefficient of the middle term, which is 14 .
| -33 | + | -1 | = | -34 | ||
| -11 | + | -3 | = | -14 | ||
| -3 | + | -11 | = | -14 | ||
| -1 | + | -33 | = | -34 | ||
| 1 | + | 33 | = | 34 | ||
| 3 | + | 11 | = | 14 | That's it |
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 3 and 11
x2 + 3x + 11x + 33
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x+3)
Add up the last 2 terms, pulling out common factors :
11 • (x+3)
Step-5 : Add up the four terms of step 4 :
(x+11) • (x+3)
Which is the desired factorization
Final result :
(x + 11) • (x + 3)
