The value of x such that:
2(x-4) - 3(x+1) = 4
the value of x such that (1+3+..+99)x=(2+4+...+100)
Find the value of m such that x^4– mx^2 + 6 is divisible by x^2 – 1. Answer: m =
x4 - mx2 + 9 = (x2 -1)2
vây m =6 thì x4 -6x2 +9 chia hết cho x2 - 1

The value of x such that (x - 4) +8 =2x
(x - 4) + 8 = 2x
=> x - 4 + 8 = 2x
=> x - 2x = -8+4
=> -x = -4
=> x = 4
\(\left(x-4\right)+8=2x\)
\(\Rightarrow x-4+8=2x\)
\(\Rightarrow x+4=2x\)
\(\Rightarrow2x-x=4\)
\(\Rightarrow x=4\)
Given x,y such that x^2-y^2=2. The value of expression A=2(x^6-y^6)-6(x^4+y^4)
x^2-y^2=2=(x-y).(x+y)

x-y 1 2 -1 -2
y+x 2 1 -2 -1

y 0.5 -0.5
find the negative value of x such that |x4+|2x+3|+4|=(-x2)2 +9
Tìm giá trị âm của x sao cho ......
x= -4
giải
\(\left|x^4+\left|2x+3\right|+4\right|=\left(-x\right)^4+9\)
=>\(\left|2x+3\right|+4=9\)
=>\(\left|2x+3\right|\)=5
Xét hai trường hợp:
TH1
2x+3=5
=>2x=2 =>x=1(ko thỏa mãn)
TH2
2x+3=-5
2x=-8 => x=-4(Thỏa mãn)
Vậy x=-4
OK có gì ko hiểu cứ hỏi mình nhé
Find the value of k such that x3 + kx2 + (4 - k)x - 35 is divisible by x - 7.
Answer: k = ........
Dịch: Tìm giá trị của k nếu :\(x^3+kx^2+\left(4-k\right)x-35⋮\left(x-7\right)\)
=>x-7=0=>x=7 => Là nghiệm của phương trình .
Thế x=7 vào biểu thức , ta có :
\(7^3+k.7^2+\left(4-k\right).7-35\)
=\(343+49k+28-7k-35=>42k=-336=>k=-8\)
Vậy k=-8
Find the value of such that
The value of x such that \(1\frac{1}{4}x+\frac{1}{3}=\frac{6}{15}\) is
(round to three decimal places)
