Step by Step Solution
Step 1 :
Trying to factor by splitting the middle term
1.1 Factoring -x2+2x+12
The first term is, -x2 its coefficient is -1 .
The middle term is, +2x its coefficient is 2 .
The last term, "the constant", is +12
Step-1 : Multiply the coefficient of the first term by the constant -1 • 12 = -12
Step-2 : Find two factors of -12 whose sum equals the coefficient of the middle term, which is 2 .
-12 | + | 1 | = | -11 | ||
-6 | + | 2 | = | -4 | ||
-4 | + | 3 | = | -1 | ||
-3 | + | 4 | = | 1 | ||
-2 | + | 6 | = | 4 | ||
-1 | + | 12 | = | 11 |
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
-x2 + 2x + 12
