Question

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

Answer 1

Answer:

$\frac{6z-5}{z+5}$

Step-by-step 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

$\frac{2(6z-5)}{2(z+5)}$ ← cancel the 2 on numerator/ denominator

= $\frac{6z-5}{z+5}$
