Question

Number of rational roots of (2x+3) (2x+5) (x-1) (x-2)

Answer 1

Answer:

there are 4 rational roots.

Step-by-step explanation:

Let,

P(x)=(2x+3)(2x+5)(x-1)(x-2)

For roots, P(x)=0

implies,

(2x+3)(2x+5)(x-1)(x-2)=0

hence,

either 2x+3=0 or 2x+5=0 or (x-1)=0 or (x-2)=0

therefore, roots are

x= -3/2 , -5/2 , 1 , 2

Hence, 4 rational roots are there.
