Other Ways to Solve
Simplification or other simple resultsStep by Step Solution
Step 1 :
Equation at the end of step 1 :
(8+((3•(x-2))•x))+5•(x+3)
Step 2 :
Equation at the end of step 2 :
(8+(3•(x-2)•x))+5•(x+3)
Step 3 :
Equation at the end of step 3 :
(8 + 3x • (x - 2)) + 5 • (x + 3)
Step 4 :
Trying to factor by splitting the middle term
4.1 Factoring 3x2-x+23
The first term is, 3x2 its coefficient is 3 .
The middle term is, -x its coefficient is -1 .
The last term, "the constant", is +23
Step-1 : Multiply the coefficient of the first term by the constant 3 • 23 = 69
Step-2 : Find two factors of 69 whose sum equals the coefficient of the middle term, which is -1 .
| -69 | + | -1 | = | -70 | ||
| -23 | + | -3 | = | -26 | ||
| -3 | + | -23 | = | -26 | ||
| -1 | + | -69 | = | -70 | ||
| 1 | + | 69 | = | 70 | ||
| 3 | + | 23 | = | 26 | ||
| 23 | + | 3 | = | 26 | ||
| 69 | + | 1 | = | 70 |
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
3x2 - x + 23
