Question

Jawabannya apa ya yang tau tolong jawabdp

Answer 1

(2x+3y)(px+qx)=rx^2+23xy+12y^2
<=> 2px^2+2qxy+3pxy+3qy^2
<=> 2px^2+(2q+3p)x-y+3qy^2

3qy^2=12y^2
<=> 3q=12
<=> q= 12/3
<=> q=4

(2q+3p)xy=23xy
<=> 2.4+3p=23
<=>8+3p=23
<=> 3p=23-8
<=> p= 15/3
<=> p=3

2px^2=rx^2
<=> 2.3=2r
<=>6=2r
<=> r=6/2
<=> r=3
