Half the x-coefficient is -3, so the equation needs to be rearranged into a form that looks like
x² -6x +(-3)² + [something]
You can get there by adding and subtracting 9 from the original equation.
y = x² -6x +9 +7 -9 . . . . . 9 added and subtracted
y = (x² -6x +9) -2
The quantity in parentheses is a perfect square, so we can write the equation in the desired form as ...
y = (x -3)² -2
20 x .80 = 16
So the answer would be 16.
I hope this helps :)
Answer:
x = 1/2
Step-by-step explanation:
<em>Simplify the sides of the equation...</em>
<em>10x + 3 = 4x + 6</em>
<em>Subtract 3 from both sides...</em>
<em>10x = 4x + 3</em>
<em>Subtract 4x from both sides...</em>
<em>6x = 3</em>
<em>Divide by 6</em>
<em>x = 1/2</em>
