$\bf{1) \ x^4-61x^2+900=0 }$

Applying the factorization method, for example:

$\bf{ 0=(x^2)^2-61(x^2)+900=(x^2-36)(x^2-25)}$

$\bf{\\ &=(x+6)(x-6)(x+5)(x-5); }$

$\bf{ x_1=6 \quad x_2=-6 \quad \ \ \ x_3=5 \quad x_4=5 }$

$\bf{2) \ x^4-25x^2+144=0 }$

Applying the factorization method:

$\bf{0&=(x^2)^2-25(x^2)+144=(x^2-16)(x^2-9) }$

$\bf{ =(x-4)(x+4)(x-3)(x+3); }$

$\bf{ x_1=4 \quad x_2=-4 \quad x_3=3 \quad x_4=-3 }$

-2/3x + 2.8 = -8.2 what is x

JulsSmile [24]

-2/3x + 2.8 = -8.2 what is x
Add 2.8 on both side of the equation
-2/3x=-11
Divide both side by -2/3
x=33/2

Check: -2/3(33/2)+ 2.8 = -8.2
-11+2.8=-8.2
-8.2=-8.2

Answer is x=33/2

Cho hai biến cố xung khắc và B, sao cho ( ≠ 0), ( ≠ 0). Hỏi A và B có độc lập không?

romanna [79]

Answer:

Ta có: P ( A ) P ( B ) = 0 , 12 . Vì P ( A B ) = 0 , 2 ≠ 0 , 12 = P ( A ) P ( B )

nên hai biến cố A và B không độc lập với nhau.
