Answer 2

Answer:

(b) 2

Step-by-step explanation:

The question says:

2x²+x= 10

Make it a quadratic equation:

2x²+x-10=0

Splitting its middle term:

2x²-4x+5x-10=0

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

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

Therefore,

1) 2x+5=0

x= -5/2

2) x-2= 0

x= 2

As the question number is a whole number, we'll take x=2.

Verification:

LHS= 2x²+x= 2(2)²+(2)= 8+2= 10

RHS= 10

Hence, LHS=RHS=10

Therefore, (b) 2 is the correct answer...
