factorize:x²+100x-150000
Answers
Answer:
Factoring x2+100x-150000
The first term is, x2 its coefficient is 1 .
The middle term is, +100x its coefficient is 100 .
The last term, "the constant", is -150000
Step-1 : Multiply the coefficient of the first term by the constant 1 • -150000 = -150000
Step-2 : Find two factors of -150000 whose sum equals the coefficient of the middle term, which is 100 .
-150000 + 1 = -149999
-75000 + 2 = -74998
-50000 + 3 = -49997
-37500 + 4 = -37496
-30000 + 5 = -29995
-25000 + 6 = -24994
For tidiness, printing of 54 lines which failed to find two such factors, was suppressed
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
