Answer: x2 + 34x - 13

Explanation:

STEP

1

Trying to factor by splitting the middle term

1.1 Factoring x2+34x-13

The first term is, x2 its coefficient is 1 .

The middle term is, +34x its coefficient is 34 .

The last term, "the constant", is -13

Step-1 : Multiply the coefficient of the first term by the constant 1 • -13 = -13

Step-2 : Find two factors of -13 whose sum equals the coefficient of the middle term, which is 34 .

-13 + 1 = -12

-1 + 13 = 12

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Final result :

x2 + 34x - 13
