Question

Solve by factorisation method
x² - 15x + 54 = 0​

Answer 1

Answer:

x=6 or x=9. Explanation: x2−15x+54=0. Factorise. x2−9x−6x+54=0. x(x−9)−6(x−9)=0. (x −6)(x−9)=0. x−6=0 or x−9=0. x=6 or x=9.

Answer 2

Answer:

(x-6)(x-9)

Step-by-step explanation:

x^2-6x-9x+54

x(x-6)-9(x-6)

(x-6)(x-9)
