Question

factorise(i) p2 - 2 25 (ii) m3 -n 3​

Answer 1

Answer:

Step-by-step explanation:

p²-25²

(p+25) (p-25)

m³-n³

(m+n) (m²-mn+n²)

Answer 2

Answer:

(i) (p+15)(p-15)

(ii) (m-n)(m²+n²+mn)

Step-by-step explanation:

Formula used-

a²-b²=(a+b)(a-b)

a³-b³=(a-b)(a²+b²+ab)

Solution-

(i) p²-225

= (p)²-(15)²

= (p+15)(p-15)

(ii) m³-n³

= (m-n)(m²+n²+mn)
