Question

The roots of the quadratic equation $p{x}^2+qx+c=0,p\ne 0$ will be given by $x=$

• A. $\frac{-q\pm \sqrt{q^2-4pc}}{2p}$
• B. $\frac{-p\pm \sqrt{p^2-4qc}}{2p}$
• C. $\frac{-p\pm \sqrt{p^2-4qc}}{2q}$

Answer 1

The correct option is A $\frac{-q\pm \sqrt{q^2-4pc}}{2p}$

Given: $p{x}^2+qx+c=0,p\ne 0$
Now, using the quadratic formula, the roots of the given quadratic equation are given by:
$x=\frac{-q\pm \sqrt{q^2-4pc}}{2p}$
