Step by Step Solution
Step 1 :
Equation at the end of step 1 :
((2•3x2) + 11x) + 4
Step 2 :
Trying to factor by splitting the middle term
2.1 Factoring 6x2+11x+4
The first term is, 6x2 its coefficient is 6 .
The middle term is, +11x its coefficient is 11 .
The last term, "the constant", is +4
Step-1 : Multiply the coefficient of the first term by the constant 6 • 4 = 24
Step-2 : Find two factors of 24 whose sum equals the coefficient of the middle term, which is 11 .
| -24 | + | -1 | = | -25 | ||
| -12 | + | -2 | = | -14 | ||
| -8 | + | -3 | = | -11 | ||
| -6 | + | -4 | = | -10 | ||
| -4 | + | -6 | = | -10 | ||
| -3 | + | -8 | = | -11 | ||
| -2 | + | -12 | = | -14 | ||
| -1 | + | -24 | = | -25 | ||
| 1 | + | 24 | = | 25 | ||
| 2 | + | 12 | = | 14 | ||
| 3 | + | 8 | = | 11 | That's it |
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 3 and 8
6x2 + 3x + 8x + 4
Step-4 : Add up the first 2 terms, pulling out like factors :
3x • (2x+1)
Add up the last 2 terms, pulling out common factors :
4 • (2x+1)
Step-5 : Add up the four terms of step 4 :
(3x+4) • (2x+1)
Which is the desired factorization
Final result :
(2x + 1) • (3x + 4)
