1.) ( 2x+3)/(x+2), (x=1)
2.) (2x^2+5x+4)/(2x+5), (x=-2)

Sagot :

Jers15viz
1.(2x+3)/(x+2), (x=1)
[2(1)+3]/(1+2)
(2+3)/(3)
=5/3

2.(2x^2+5x+4)/(2x+5), (x=-2)
[2(-2)^2+5(-2)+4]/[2(-2)+5]
[2(4)-10+4]/(-4+5)
(8-10+4)/1
2/1
=2

Hope this helps =)
1. 2(1)+3/(1)+2
    2+3/ 3
    2+1= 3
    
2. 2(2)^2+5(-2)+4 / 2(-2)+5
    4^2-10+4 / -4+5
    16-10+4 / -4+5
    16-10-1-4+5
    16-10-1+1
    16-10
    =6
