# How to solve x + x – 1 x^2 x 11 x + 3 4 ?

Welcome to my article Solve for x + x – 1 x^2 x 11 x + 3 4This question is taken from the simplification lesson.
The solution of this question has been explained in a very simple way by a well-known teacher by doing addition, subtraction, and fractions.
For complete information on how to solve this question Solve for x + x – 1 x^2 x 11 x + 3 4 read and understand it carefully till the end.

Let us know how to solve this questionSolve for x + x – 1 x^2 x 11 x + 3 4

First write the question on the page of the notebook

x + x – 1 x^2 x 11 x + 3 4 ?

can also write it like this,

\displaystyle x+x-1{{x}^{2}}\text{x }11x+34

\displaystyle x+x-11{{x}^{2}}\text{x }x+34

\displaystyle 2x-11{{x}^{2}}\text{x }x+34

To solve this question, we use this formula,

\displaystyle x=\frac{{-b\pm \sqrt{{{{b}^{2}}-4ac}}}}{{2a}}

Here, a= 2
b =-11 , c =34
Then ,

Putting the above value in the formula,

\displaystyle x=\frac{{-(-11)\pm \sqrt{{{{{(-11)}}^{2}}-4.2.34}}}}{{2.2}}

\displaystyle x=\frac{{(11)\pm \sqrt{{121-272}}}}{4}

\displaystyle x=\frac{{(11)\pm \sqrt{{-151}}}}{4}
