Answer

The simplified value of expression is $(x^{2} - 4 x + 3) - (4 x^{2} + 3 x - 5) = - 3 x^{2} - 7 x + 8$ $(x^{2} - 4 x + 3) - (4 x^{2} + 3 x - 5) = - 3 x^{2} - 7 x + 8$ .

1Step 1. Write down the given expression.

The given expression to simplify is $(x^{2} - 4 x + 3) - (4 x^{2} + 3 x - 5)$ .

2Step 2. Simplify the given expression.

Simplifying $(x^{2} - 4 x + 3) - (4 x^{2} + 3 x - 5)$ gives,

$\begin{matrix} (x^{2} - 4 x + 3) - (4 x^{2} + 3 x - 5) = x^{2} - 4 x + 3 - 4 x^{2} - 3 x + 5 \\ = (x^{2} - 4 x^{2}) + (- 4 x - 3 x) + (3 + 5) \\ = - 3 x^{2} - 7 x + 8 \end{matrix}$

3Step 3. Conclusion.

The simplified value of expression is $(x^{2} - 4 x + 3) - (4 x^{2} + 3 x - 5) = - 3 x^{2} - 7 x + 8$ .
