Tim cac so a, b, c khac 0 thoa man: a + b - 2 / c = b + c +1 / a = c + a +1 / b = a + b +c / 2
tìm a,b,c biết rằng a(a+b+c)=\(\frac{-1}{24};b\left(a+b+c\right)=\frac{1}{16};c\left(a+b+c\right)=\)\(\frac{-1}{72}\)
1, tim Abiet:A=a/b+c=c/a+b=b/c+a
tim bo ba so (a;b;c) thoa man: a+b-1/c = b+c-2/a = c+a+3/b = 2/a+b+c
a^3+3a^2+5=5^b .Biet:a+3=5^c
a,tim a biet da thuc A(x)=ax2- 1/2x +1 co 1 nghiem la -1/2
b, tim a,b cua da thuc :B(x)= ax2+bx+5 biet B(1)=6 va B(-2) = 15
c, cho da thuc C(x)= ax+b .Tim a,b biet :
x=4 la nhgiem cua C(x)va C(2)=1
a) a=a/b+c-1=b/a+c-2=c/a+b+3=a+b+c tim a,b,c
b) a+3/4=b+2/3=c-7/3 và 2a-3b+4c=-12
a) a=a/b+c-1=b/a+c-2=c/a+b+3=a+b+c tim a,b,c
b) a+3/4=b+2/3=c-7/3 và 2a-3b+4c=-12
a) a=a/b+c-1=b/a+c-2=c/a+b+3=a+b+c tim a,b,c
b) a+3/4=b+2/3=c-7/3 và 2a-3b+4c=-12
