Question

Simplify by removing factor of 1 2z-10/2z+10

Answer 1

`(6z-5)/(z+5)`

Explanation:

Factorise the numerator and denominator

12z - 10 = 2(6z - 5) ← common factor of 2

2z + 10 = 2(z + 5) ← common factor of 2

Thus the fraction becomes

`(2(6z-5))/(2(z+5))` ← cancel the 2 on numerator/ denominator

=
`(6z-5)/(z+5)`
