Question

using by Quadratic formula x^2+7x+900 ........​

Answer 1

Answer:

The first term is, x2 its coefficient is 1 .

The middle term is, +7x its coefficient is 7 .

The last term, "the constant", is -900

Step-1 : Multiply the coefficient of the first term by the constant 1 • -900 = -900

Step-2 : Find two factors of -900 whose sum equals the coefficient of the middle term, which is 7 .

-900 + 1 = -899

-450 + 2 = -448

-300 + 3 = -297

-225 + 4 = -221

-180 + 5 = -175

-150 + 6 = -144

For tidiness, printing of 21 lines which failed to find two such factors, was suppressed

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored
