Step by Step Solution
Step 1 :
Equation at the end of step 1 :
((2•7y2) - 41y) + 27
Step 2 :
Trying to factor by splitting the middle term
2.1 Factoring 14y2-41y+27
The first term is, 14y2 its coefficient is 14 .
The middle term is, -41y its coefficient is -41 .
The last term, "the constant", is +27
Step-1 : Multiply the coefficient of the first term by the constant 14 • 27 = 378
Step-2 : Find two factors of 378 whose sum equals the coefficient of the middle term, which is -41 .
| -378 | + | -1 | = | -379 | ||
| -189 | + | -2 | = | -191 | ||
| -126 | + | -3 | = | -129 | ||
| -63 | + | -6 | = | -69 | ||
| -54 | + | -7 | = | -61 | ||
| -42 | + | -9 | = | -51 | ||
| -27 | + | -14 | = | -41 | That's it |
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -27 and -14
14y2 - 27y - 14y - 27
Step-4 : Add up the first 2 terms, pulling out like factors :
y • (14y-27)
Add up the last 2 terms, pulling out common factors :
1 • (14y-27)
Step-5 : Add up the four terms of step 4 :
(y-1) • (14y-27)
Which is the desired factorization
Final result :
(14y - 27) • (y - 1)
