Question

The coefficient of t2 in the expression 3t2+2t+25 is

Answer 1

Step-by-step explanation:

3+2t+25 this the correct answer

Answer 2

Answer:

Step-by-step explanation:

Changes made to your input should not affect the solution:

(1): "t2"   was replaced by   "t^2".  

Step by step solution :

Trying to factor by splitting the middle term

2.1     Factoring  3t2-2t+25  

The first term is,  3t2  its coefficient is  3 .

The middle term is,  -2t  its coefficient is  -2 .

The last term, "the constant", is  +25  

Step-1 : Multiply the coefficient of the first term by the constant   3 • 25 = 75  

Step-2 : Find two factors of  75  whose sum equals the coefficient of the middle term, which is   -2 .

     -75    +    -1    =    -76  

     -25    +    -3    =    -28  

     -15    +    -5    =    -20  

     -5    +    -15    =    -20  

     -3    +    -25    =    -28  

     -1    +    -75    =    -76  

     1    +    75    =    76  

     3    +    25    =    28  

     5    +    15    =    20  

     15    +    5    =    20  

     25    +    3    =    28  

     75    +    1    =    76  

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored
