Step by Step Solution
Step 1 :
Trying to factor by splitting the middle term
1.1 Factoring -a2+3a+16
The first term is, -a2 its coefficient is -1 .
The middle term is, +3a its coefficient is 3 .
The last term, "the constant", is +16
Step-1 : Multiply the coefficient of the first term by the constant -1 • 16 = -16
Step-2 : Find two factors of -16 whose sum equals the coefficient of the middle term, which is 3 .
| -16 | + | 1 | = | -15 | ||
| -8 | + | 2 | = | -6 | ||
| -4 | + | 4 | = | 0 | ||
| -2 | + | 8 | = | 6 | ||
| -1 | + | 16 | = | 15 |
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
-a2 + 3a + 16
