Because 2a+8>=0, b-root number 3>=0, and the addition of two more numbers is equal to 0, so a=-4, b=root number 3, so -2x+4 root number 3=-6, so a=3+2 root number 3
-
Solution: According to the topic.
2a+8=0
a=-4b-√3=0
b = 3 because the root number is under and the absolute value is not negative.
a+2)x+4b=a-2
2x+4√3=-6
2x=4√3+6
x=2√3+3

2a+8)+|b-Root No. 3 |=0 2a+8=0 a=-4 )|b-Root No. 3 |=0 b=root3 (a+2)x+4b=a-2 deformed to -2x+4*root3 =-6 x=2*root3 +6
-
2a+8=0,a=-4
b - root number 3 = 0, b = root number 3
Generation(a+2)x+4b=a-2 gives -2x+12 root number 3=-6x=3+4 root number 3
-
Since the root number and the absolute value are not negative, only 2a plus 8 equals 0; b minus the root number 3 is equal to 0, so a is equal to minus 4, b is equal to the root number 3, substituting the following equation, we can get x is equal to 2 root number 3 plus 3. This question is quite simple, as long as you grasp the root number term and the absolute value term is not negative, it is very easy to do.

According to the title. 2a+8=0
a=-4b-√3=0
b = 3 because the value of the Wandering Root and the Absolute Fighting Shout is not negative.
a+2)x+4b=a-2
2x+4√3=-6
2x=4√3+6
x=2√3+3
-
Both the root number and the absolute value are greater than or equal to 0
The sum is equal to 0, if there is a large hail sign of 0, then the other is less than 0, which is not true.
So both are equal to 0
So 2a+8=0, b- 3=0
a=-4,b=√3
a+2=-2,b²=3
Therefore, the party dispatch lease is -2x+3=-4-1=-5
x=4,2,
-
The two sides hold the reed square.
a^2-2a-b=a^2
2a+b=0
Divide by b to get the paragraph carefully:
2a/b+1=0
a/b=-1/2
-
The root number b=2 then spring or absolute b=4
a|=3a=±3
ab>0
Tuan Zhao A, B with the same number of pickpockets.
So a=3, so a-b
-
Knowing a>b>0, verify a+b+3> root number ab+2 root number A + root number b
a+b+2-2 (root number a + root number b) = (a) -2 a+1+( b) -2 b+1=( a-1) +b-1) >0 a+b+2 old withering = 2 (root number a + root number b) by asking for service before the difference is larger than the defeat.

Root number 2a-8 + b-1 = 0
The root band number 2a-8 = 0 and the excitation chain reed b-1 = 0 (both the root number and the absolute value are non-negative numbers).
2a-8=0,b-1=0
a=4,b=1
-
(4a-b+1)+(a+2b+7) 2=0 4a-b+1=0(1) and a+2b+7=0 (2)1) 2+(2): 9a+9=0
Poor scum repentance shirt a=-1, b=-3
2a√(b/a)*√b)=-2√3×√3=-6
-
The root number is 2a+8+|b-Root No. 3 |=0, then 2a+8=0 b- 3=0
a= -4 b=√3
Substituting into the equation yields:
4+2)x+(√3)²= -4-1
2x+3= -5
2x= -8x=4
Firstly, a3b+ab3-2a2b+2ab2=7ab-8 is transformed into ab(a-b-1)2+2(ab-2)2=0 by extracting the common factor, using the perfect flat method, and adding terms to obtain a-b=1 and ab=2 according to the properties of a and b being positive and non-negative numbers, and then solving the values of a and b, and substituting a2-b2 to obtain the result >>>More
If a, b are positive real numbers.
satisfying ab=a+b+3, find the range of ab. >>>More
Since sin = root number 2cos, so sin 2 = 2cos 2, then cos 2 = 1-2cos 2 >>>More
Proof: From the title, it can be seen that 0<=a<=1,0<=b<=1; >>>More
By |a+b-3|+(a-b+1)=0, when a+b-3>=0, the original formula =a+b-3+a-b+1=0, a=1, b>=2; >>>More
