Answer:

2x2 + 11x - 1

Explanation:

Step 1 :

Equation at the end of step 1 :

(6x + 4) + ((2x2 + 5x) - 5)

Step 2 :

Trying to factor by splitting the middle term

2.1 Factoring 2x2+11x-1

The first term is, 2x2 its coefficient is 2 .

The middle term is, +11x its coefficient is 11 .

The last term, "the constant", is -1

Step-1 : Multiply the coefficient of the first term by the constant 2 • -1 = -2

Step-2 : Find two factors of -2 whose sum equals the coefficient of the middle term, which is 11 .

-2 + 1 = -1

-1 + 2 = 1

i also found out: ⬇️

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Final result :

2x2 + 11x - 1

Answer:

2x^2 +11x-1

Explanation:

(6x- - 4) + (2x^2 + 5x - 5)

Subtracting a negative is adding

(6x+ 4) + (2x^2 + 5x - 5)

Combine like terms

2x^2 +5x+6x +4-5

2x^2 +11x-1
