respondam a 3 por favorfavor

Answer 1

+15x²-11x+2=0
Por Báskara
Δ=b²-4.a.c
Δ=(-11)²_4.15.2
a=15,b=-11,c=2
Δ=121-120
Δ=1
x1=(-b+√Δ):2.a
x1=(+11+1):2.15
x1=12/30=6/15=2/5
x2=10/30=1/3
1/p+1/q=sendo p e q raizes da equação
1/2/5+1/1/3=
1.5/2+1.3/=5/2+3/1= mmc de 2,3=6
    
15/6+18/6=33/6=5.5
 Resposta 5.5
