Answer:
= x^2 - 21x + 108
= x^2 - 12x - 9x + 108
= x(x-12) - 9(x-12)
= (x-9) (x-12)
= x-9 =
x = 9
And x-12 =
x = 12
Hence x = 9 or x = 12.

Answer:
x = 9
x =12
Step-by-step explanation:
x^2-21x+108 =0
x^2 -x(12+9) +108=0
x^2-12x -9x + 108 = 0
x(x-12) -9(x-12) = 0
(x-9) (x-12) =0
x-9=0
x = 9
x-12=0
x=12
