Equation: \frac{13}{15} - \frac{1}{5}

When adding or subtracting, you have to make sure they have a common denominator

So you have to multiply \frac{1}{5} by \frac{3}{3}

\frac{1}{5} * \frac{3}{3} = \frac{3}{15}

Since they both have the same denominator, you subtract

\frac{13}{15} - \frac{3}{15} = \frac{10}{15}

One thing to note is when subtracting, you DO NOT subtract the denominator, only the numerators

To reduce to the lowest terms, you need to find a common factor.
5 goes into 10 two times and goes into 15 three times

10 ÷ 5=2

15 ÷ 5=3

That leaves it with the fraction \frac{2}{3}

Answer: \frac{2}{3}

If x-y=9 and xy=2,find the value of (x square + y square)
kati45 [8]

Answer:

x² + y² = 85

Step-by-step explanation:

Using the expansion

(x - y)² = x² + y² - 2xy , then

x² + y² - 2xy = (x - y)² ( add 2xy to both sides )

x² + y² = (x - y)² + 2xy ← substitute given values

          = 9² + 2(2)

          = 81 + 4

          = 85
