The solution of 5x^2–3(x–2)+x for x = 3 is 45

<u>Solution:</u>

In this question we have been given an equation and asked to solve for a particular value of ‘x’.

The given equation is:

5x^{2}-3(x-2)+x

We have been asked to solve it for x=3.

So, we need to substitute the value of x as 3 in the equation and then simplify it as follows:

\begin{array}{l}{=5\left(3^{2}\right)-3(3-2)+3} \\\\ {=5(9)-3(1)+3} \\\\ {=45-3+3=45}\end{array}

Therefore, on solving the equation for x = 3 we get 45
