Question

Factorise:
(i) x²-y²/9
(ii) 2x²-7x-15

Answer 1

X^2 - Y^2/9
= (X+Y/3)(X-Y/3)

Answer 2

☆Hello friend☆
(i) Factorisation= a^2-b^2=(a+b)(a-b)

${x}^{2} - \frac{ {y}^{2} }{9} \\ {x}^{2} - { (\frac{y}{3} )}^{2}$
(x+y/3)(x-y/3)

(ii) Factorisation=

$2 {x}^{2} - 7x - 15$

2x^2 -10x+3x-15
2x(x-5) +3(x-5)
(2x+3)(x-5)

Hope it helps
