Answer 2

Answer:

Factoring x2-8x-480

The first term is, x2 its coefficient is 1 .

The middle term is, -8x its coefficient is -8 .

The last term, "the constant", is -480

Step-1 : Multiply the coefficient of the first term by the constant 1 • -480 = -480

Step-2 : Find two factors of -480 whose sum equals the coefficient of the middle term, which is -8 .

-480 + 1 = -479

-240 + 2 = -238

-160 + 3 = -157

-120 + 4 = -116

-96 + 5 = -91

-80 + 6 = -74

For tidiness, printing of 18 lines which failed to find two such factors, was suppressed

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Equation at the end of step

:

x2 - 8x - 480 = 0
