Pulling out like terms
3.1 Pull out like factors :
-11x2 + 7x - 1 = -1 • (11x2 - 7x + 1)
Trying to factor by splitting the middle term
3.2 Factoring 11x2 - 7x + 1
The first term is, 11x2 its coefficient is 11 .
The middle term is, -7x its coefficient is -7 .
The last term, "the constant", is +1
Step-1 : Multiply the coefficient of the first term by the constant 11 • 1 = 11
Step-2 : Find two factors of 11 whose sum equals the coefficient of the middle term, which is -7 .
-11 + -1 = -12
-1 + -11 = -12
1 + 11 = 12
11 + 1 = 12
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
-11x2 + 7x - 1
