Is the following equation a quadratic equation?

$43x −85x_{2} =87 $

(a)

Yes

(b)

No

(c)

Ambiguous

(d)

Data insufficient

Correct answer: (a)

Solution: Given, $43x −85x_{2} =87 $

Hence, $6x−5x_{2}=7$

$⇒5x_{2}−6x+7=0$

$⇒ax_{2}+bx+c=0$

Hence, it is a quadratic equation.

Hence, $6x−5x_{2}=7$

$⇒5x_{2}−6x+7=0$

$⇒ax_{2}+bx+c=0$

Hence, it is a quadratic equation.
