Answer 1

Answer:

x= 5 /2 , − 4

Step-by-step explanation:

Factor and set each factor equal to zero.

Answer 2

Answer: x=-4, x=5/2

Step-by-step explanation:

To factor the expression, you want to break up the expression into 2 parts.

2x²+3x-20

(2x²-5x)+(8x-20)       [factor each part]

x(2x-5)+4(2x-5)         [take out x+4]

(x+4)(2x-5)                 [set each factor equal to 0]

x=-4

x=5/2

Now, we know that x=-4 and x=5/2.
