Answer:
x2 - 9x - 11
Step-by-step explanation:
Step 1 :
Equation at the end of step 1 :
((((2x2 - 4x) - 3) - x2) - 5x) - 8
Step 2 :
Trying to factor by splitting the middle term
2.1 Factoring x2-9x-11
The first term is, x2 its coefficient is 1 .
The middle term is, -9x its coefficient is -9 .
The last term, "the constant", is -11
Step-1 : Multiply the coefficient of the first term by the constant 1 • -11 = -11
Step-2 : Find two factors of -11 whose sum equals the coefficient of the middle term, which is -9 .
-11 + 1 = -10
-1 + 11 = 10
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
x2 - 9x - 11
