3x^2-7x-4
Step by Step Solution
Step 1 :
Equation at the end of step 1 :
((((4x - 10) + 2x2) + 6) - 11x) + x2
Step 2 :
Trying to factor by splitting the middle term
2.1 Factoring 3x2-7x-4
The first term is, 3x2 its coefficient is 3 .
The middle term is, -7x its coefficient is -7 .
The last term, "the constant", is -4
Step-1 : Multiply the coefficient of the first term by the constant 3 • -4 = -12
Step-2 : Find two factors of -12 whose sum equals the coefficient of the middle term, which is -7 .
| -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 :
3x2 - 7x - 4
