Q12. Write the equation y=x2-6x+11 in... [FREE SOLUTION]

Chapter 8: Q12. (page 424)

Write the equation $y = x^{2} - 6 x + 11$ in standard form.

Short Answer

Expert verified

The required form of the equation in standard form $y = a {(x - h)}^{2} + k$ is $y = {(x - 3)}^{2} + 2$ where $a = 1, h = 3 and k = 2$ .

Step by step solution

Step 1. Write down the given information.

The given equation is $y = x^{2} - 6 x + 11$ .

Step 2. Calculation.

The given equation $y = x^{2} - 6 x + 11$ is converted to standard form $y = a {(x - h)}^{2} + k$ as:

$\begin{matrix} y = x^{2} 鈭� 6 x + 11 \\ = x^{2} 鈭� 6 x + 11 + {(鈭� 3)}^{2} 鈭� {(鈭� 3)}^{2} .... (\begin{array}{l} Addand \\ subtract {(鈭� 3)}^{2} \end{array}) \\ = (x^{2} 鈭� 6 x + {(鈭� 3)}^{2}) + (11 鈭� {(鈭� 3)}^{2}) \\ = {(x 鈭� 3)}^{2} + 2 \end{matrix}$

Here $a = 1, h = 3 and k = 2$ .

Step 3. Conclusion.

The required form of the given equation is $y = {(x - 3)}^{2} + 2$ where $a = 1, h = 3 and k = 2$ .
