Answer 1

D)
`x=(5)/(3)` and
`x=-4`

Explanation:

Factor by grouping

`3x^2+7x-20=0\\\\3x^2+12x-5x-20=0\\\\3x(x+4)-5(x+4)=0\\\\(3x-5)(x+4)=0`

Solve each factor using the Zero Product Property

`3x-5=0\\\\3x=5\\\\x=(5)/(3)`

`x+4=0\\\\x=-4`

Thus,
`x=(5)/(3)` and
`x=-4` are the solutions

Answer 2

The answer is D as you can see in the picture
