faktorkanlah bentuk bentuk aljabar berikut 1.2x²+7x+3 2.2x²+5x+3 3.3y²+8y+4 4.5x²+13x+6 5.3y²-8y+4 tolong jwab pake caranya

1.2x²+7x+3

<==> ( 2x+1)(x+3)

*2x+1 = 0
2x = -1
x = - 1/2

*x+3=0
x= -3


2.2x²+5x+3

<==> (2x+3)(x+1)

*2x+3 = 0
2x = -3
x = - 3/2

*x+1=0
x= -1


3.3y²+8y+4

<==> (3y+2)(y+2)

*3y+2 = 0
3y = -2
y = - 2/3

*y+2=0
y= -2


4.5x²+13x+6

<==> (5x+3)(x+2)

*5x+3 = 0
5x = -3
x = - 3/5

*x+2=0
x= -2


5.3y²-8y +4

<==> (3y-2)(y-2)

*3y-2 = 0
3y = 2
y = 2/3

*y-2=0
y = 2

Semoga membantu
