In the first one, the last two equations are correct

 

In the second one, the second and  fourth equations are correct

 

 

(3x - 5) (2x - 7) =  6x^2 - 10x - 21x + 35  = 6x^2 - 31x + 35

 

(x + 3) ( -2x^2 + 2x + 5)  =

 

x* -2x^2  + x * 2x  + x *5   =   -2x^3 + 2x^2  + 5x

3 * -2x^2 + 3 *2x  + 3 *5  =              - 6x^2   + 6x  + 15

                                              ____________________

                                                -2x^3 - 4x^2 + 11x + 15

 

None of the answers for the last are  correct ....!!!!
