Answer:
plz mark me as brainliest
Step-by-step explanation:
The first term is, x2 its coefficient is 1 .
The middle term is, -6x its coefficient is -6 .
The last term, "the constant", is -1
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 -6 .
-1 + 1 = 0
Observation : No two such factors can be found !!
