Answer 2

Answer:

$0$

Explanation:

Step : 1  Quadratic equations refer to equations containing at least one term that is squared. Its standard form is ax² + bx + c = 0 where a, b, and c are constants and x is an unknown quantity.

Let us now translate the given verbal sentences to mathematical sentence and express them into quadratic equations.

Let the frame's width be ' x '

$\therefore \text { length }=(x+1)$

Now area $=12$.

Step : 2 A mathematical expression is a phrase that has a minimum of two numbers or variables and at least one mathematical operation. Let's examine the writing of phrases. The other number is x, and a number is 6 greater than half of it.

$\begin{aligned}& \therefore \quad x(x+1)=12 \\& \Rightarrow x^2+x=12 \\& \Rightarrow x^2+x-12=0\end{aligned}$

Hence, the correct answer is $0$.
