Thank you

anonymous · Answer

Pulling out like terms :

1.2   Pull out like factors:  

-3x2 + 30x - 74 = -1•(3x2 - 30x + 74)
Trying to factor by splitting the middle term

1.3    Factoring    3x2 - 30x + 74

Method : Factoring by splitting the middle term

The first term is    3x2  ,its coefficient is  3 
The middle term is   -30x  ,its coefficient is -30 
The last term, also called 'the constant', is  +74

Step-1   : Multiply the coefficient of the
           first term by the constant

                3 • 74 = 222

Step-2   : Find two factors of  222  whose  
           sum equals the coefficient of the 
           middle term, which is -30
