We have that
x²<span>-6x+7=0
</span>Group terms that contain the same variable
(x²-6x)+7=0
Complete the square Remember to balance the equation
(x²-6x+9-9)+7=0
Rewrite as perfect squares
(x-3)²+7-9=0
(x-3)²-2=0
(x-3)²=2
(x-3)=(+/-)√2
x=(+/-)√2+3
the solutions are
x=√2+3
x=-√2+3
Answer: 11/12
Step-by-step explanation:
1. To solve this problem you can transform the mixed numbers given in the problem to fractions, as you can see below:
3 2/3=(3*3+2)/3=11/3
2 3/4=(4*2+3)/4=11/4
2. Now you must make the substraction of the fraction:
11/3-11/4=11/12
3. Therefore, the answer is 11/12
