1-)4x - 9=(2x-3)(2x+3)

2x - 3

2-)(2a-3) - (a-2)=

=(2a-3) – (a-2)
=[(2a-3)-(a-2)].[(2a-3)+(a-2)]
=(2a-3-a+2).(2a-3+a-2)
=(a-1).(3a-5)

3-)(2x-3)-1=

= (2x-3)-1
=[(2x-3)-1].[(2x-3)+1]
=(2x-3-1).(2x-3+1)
=(2x-4).(2x-2)
=4(x-2).(x-1)

4-)(298-98)-200.392 =16 (1994/ÖSS)
2a
= (298-98)(298+98)-200.392 =16
2a
= 200.396-200.392 =16
2a
=200(396-392) =16
2a
=100.4 =16 a=100.4 a=25
a 16a - b İFADESİNİ ÇARPANLARA AYIRMA
