-9x^2+x+15
Step by Step Solution
Step 1 :
Equation at the end of step 1 :
(9x + 9) + (((0 - 32x2) - 8x) + 6)
Step 2 :
Trying to factor by splitting the middle term
2.1 Factoring -9x2+x+15
The first term is, -9x2 its coefficient is -9 .
The middle term is, +x its coefficient is 1 .
The last term, "the constant", is +15
Step-1 : Multiply the coefficient of the first term by the constant -9 • 15 = -135
Step-2 : Find two factors of -135 whose sum equals the coefficient of the middle term, which is 1 .
| -135 | + | 1 | = | -134 | ||
| -45 | + | 3 | = | -42 | ||
| -27 | + | 5 | = | -22 | ||
| -15 | + | 9 | = | -6 | ||
| -9 | + | 15 | = | 6 | ||
| -5 | + | 27 | = | 22 | ||
| -3 | + | 45 | = | 42 | ||
| -1 | + | 135 | = | 134 |
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
-9x2 + x + 15
