Question

Find the values of a, b, c for the quadratic equation $2x^2=x+3$ by comparing with standard form $a{x}^2+bx+c=0$.

Answer 1

Given quadratic equation is, $2x^2=x+3$

$2x^2-x-3=0$, take all the terms to left hand side

$\Rightarrow 2x^2+(-1)x+(-3)=0$

Comparing with $a{x}^2+bx+c=0$ we get

$a=2,b=-1,c=-3$
