mohon bantu saya cara menyelesaikannya 1.x²-7x-22 2.a²+9a-10 3.6-7k-k² 4.c²-14c+45 5.m²+8m+12 6.35+12y+y² 7.x²+24x+80 8.x²-49x+360 9.y²-68y+256 10.x²-21x-21

2.)a^2+9a-10
=a^2+10a-a-10
=a.(a+10)-(a+10)
=(a-1).(a+10)
4.)c^2-14c+45
=c^2-5c-9c+45
=c.(c-5)-9(c-5)
=(c-9).(c-5)
5.)m^2+8m+12
=m^2+6m+2m+12
=m.(m+6)+2(m+6)
=(m+2).(m+6)
6.)35+12y+y^2
=y^2+12y+35
=y^2+7y+5y+35
=y.(y+7)+5(y+7)
=(y+5.(y+7)
