​

Answer 1

Answer:

prefer to it child

Step-by-step explanation:

Factoring 11x2+18x-120

The first term is, 11x2 its coefficient is 11 .

The middle term is, +18x its coefficient is 18 .

The last term, "the constant", is -120

Step-1 : Multiply the coefficient of the first term by the constant 11 • -120 = -1320

Step-2 : Find two factors of -1320 whose sum equals the coefficient of the middle term, which is 18 .

-1320 + 1 = -1319

-660 + 2 = -658

-440 + 3 = -437

-330 + 4 = -326

-264 + 5 = -259

-220 + 6 = -214

For tidiness, printing of 26 lines which failed to find two such factors, was suppressed

Observation : No two such factors can be found !!
