Answer:
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "x2" was replaced by "x^2".
STEP
1
:
Equation at the end of step 1
(3x2 - 2x) - 9
2
Trying to factor by splitting the middle term
2.1 Factoring 3x2-2x-9
The first term is, 3x2 its coefficient is 3 .
The middle term is, -2x its coefficient is -2 .
The last term, "the constant", is -9
Step-1 : Multiply the coefficient of the first term by the constant 3 • -9 = -27
Step-2 : Find two factors of -27 whose sum equals the coefficient of the middle term, which is -2 .
-27 + 1 = -26
-9 + 3 = -6
-3 + 9 = 6
-1 + 27 = 26
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
