9x
pls mark as brainliest
Step-by-step explanation:
Factoring x2-9x-1
The first term is, x2 its coefficient is 1 .
The middle term is, -9x its coefficient is -9 .
The last term, "the constant", is -1
A/Q
Step-1 : Multiply the coefficient of the first term by the constant 1 • -1 = -1
Step-2 : Find two factors of -1 whose sum equals the coefficient of the middle term, which is -9 .
-1+1=0
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
x2 - 9x - 1 = 0
