2
1/2
-1/2
-2​

Answer 1

Answer:

1/2

Step-by-step explanation:

The Polynomial is 2x²+7x-4

According to Middle term splitting

The product must be -8 and the numbers we are multiplying must be 7 on adding. So the Numbers are

-1 and 8

2x²+8x-x-4=0

2x(x+4)-1(x+4)=0

(x+4)(2x-1)=0

x = -4,+1/2

The answer Is 1/2
