Question

Is the following equation a quadratic equation?

$\frac{3x}{4}-\frac{5x^2}{8}=\frac{7}{8}$

• A. Yes
• B. No
• C. Ambiguous
• D. Data insufficient

Answer 1

Answer: (A)

Yes

Given, $\frac{3x}{4}-\frac{5x^2}{8}=\frac{7}{8}$
Hence, $6x-5x^2=7$
$\Rightarrow 5x^2-6x+7=0$
$\Rightarrow a{x}^2+bx+c=0$
Hence, it is a quadratic equation.
