Question

The reduced form of $(2x-1{)}^2=x^2+2$ is not a quadratic equation.

• A. True
• B. False

Answer 1

The correct option is B False

$(2x-1{)}^2=4x^2+1–4x$
So, the above equation reduces to $(2x-1{)}^2=x^2+2$
$\Rightarrow 4x^2+1–4x=x^2+2$
$\Rightarrow 3x^2–4x–1=0$ This is a quadratic equation, because, the highest power of the variable, x, is 2
