Question

If quadratic equations ${2x}^2-3x+5=0$ and ${ax}^2-bx+c=0,a,b,cϵN$ have a common root then the value of a+b+c can be equal to

• A. 10
• B. 15
• C. 20
• D. 25

Answer 1

Answer: (A)

10

We have,

$2x^2-3x+5=0$ on comparing that and we get,

$a{x}^2-bx+c=0$

$a=2,b=3,c=5$

Then,

$a+b+c=2+3+5=10$

Hence, this is the answer.
