#### Solve simultaneous linear equations:

(i) 2a^{2}x – bx + 2a^{2} – b

(ii) p^{2} – (a + 2b)p + 2ab

**Solution:**

(i) 2a^{2}x – bx + 2a^{2} – b

Rearrange the above terms we get,

2a^{2}x + 2a – bx – b

Take out common in both terms,

2a^{2}(x + 1) – b(x + 1)

(x + 1) (2a^{2} – b)

(ii) p^{2} – (a + 2b)p + 2ab

p^{2} – (a + 2b)p + 2ab

Above terms can be written as,

p^{2} – ap – 2bp + 2ab

Take out common in both terms,

p(p – a) – 2b(p – a)

(p – a) (p – 2b)
