Answer 1

Answer:

D)  $x=\frac{5}{3}$ and $x=-4$

Step-by-step 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

$3x-5=0\\\\3x=5\\\\x=\frac{5}{3}$

$x+4=0\\\\x=-4$

Thus, $x=\frac{5}{3}$ and $x=-4$ are the solutions

Answer 2

The answer is D as you can see in the picture
