Other Ways to Solve:
Step by Step Solution
Step 1 :
Equation at the end of step 1 :
(18y + 32y2) - 22
Step 2 :
Trying to factor by splitting the middle term
2.1 Factoring 9y2+18y-22
The first term is, 9y2 its coefficient is 9 .
The middle term is, +18y its coefficient is 18 .
The last term, "the constant", is -22
Step-1 : Multiply the coefficient of the first term by the constant 9 • -22 = -198
Step-2 : Find two factors of -198 whose sum equals the coefficient of the middle term, which is 18 .
| -198 | + | 1 | = | -197 | ||
| -99 | + | 2 | = | -97 | ||
| -66 | + | 3 | = | -63 | ||
| -33 | + | 6 | = | -27 | ||
| -22 | + | 9 | = | -13 | ||
| -18 | + | 11 | = | -7 | ||
| -11 | + | 18 | = | 7 | ||
| -9 | + | 22 | = | 13 | ||
| -6 | + | 33 | = | 27 | ||
| -3 | + | 66 | = | 63 | ||
| -2 | + | 99 | = | 97 | ||
| -1 | + | 198 | = | 197 |
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
9y2 + 18y - 22
