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 ....!!!!
