Answer 1

Answer:

$\sf{x}^{2} - 30x + 216 \\</p><p></p><p> \sf= {x}^{2} - 18x - 12x + 216 \\ </p><p></p><p>\sf=x(x - 18) - 12(x - 18) \\ </p><p></p><p>\sf= (x - 18)(x - 12)$

Answer 2

Step-by-step explanation:

Q. Factorise X²+30x+216

=> X²+30x+216

=> x²+18x+12x+216

=> x(x+18)+12(x+18)

=> (x+12) (x+18)

=> x= -12, -18
