Simplify: 1/(x-y)(x-z) + 1/(y-z)(x-z)I thought it wass a partial fraction. However, it is not since the second denominator has no x, (y-z).
`1/((x-y)(x-z)) + 1/((y-z)(x-z))`
Find the lowest common denominator (LCD): (x-y)(x-z)(y-z)
Apply the LCD to each part of the fraction:
Remove the brackets from the numerator:
The 'y' will cancel out from the numerator
Rearrange the numerator:
The (x-z) from the numerator cross cancels with the denominator
