Question

Simplify -3(x + 3) + 4x

Answer 1

Answer: x2 + 34x - 13

Step-by-step 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
