This question uses the common factor method to extract a b
The answer is as follows: 2b 2+6ab-b=b(2b+6a-1) This macro school is the concept of the common factor method: if the items of the polynomial have a common factor, you can cover it to put the common factor out of the brackets, and write the polynomial in the form of the product of the cause spike cluster, and this method of factoring is called the common factor method.

Anonymous users2024-02-05Eq. (b) 2 - b 2 can be divided into two parts:
b) 2: This is an additive operation, and b is added to the cavity bridge and divided by 2.
b 2: This is a subtraction operation, divide b by 2 and then take the opposite number of the song band.
Therefore, the end result is ( b) 2 - b 2 = b - b) 2 = 2.

Reference: fooks
25%b+2=b -75%b =-2 b =8/3
b*25%+2=b b* b=-2/ b=-8
Solution: b 25%+2=0 b 25%=-2 b=-8 solution: b 25%+2=b 2=b 75% b=3 8 either one
2010-05-23 14:31:29 Added:
In solution 2, b = 8 3, typo error.
b*25%+2=b b=-2 b=8 Stir up jujube 3
b*25%+2= b=? b*25%+2=b b* b*25%+2=0 b* b* b=-32
b*25%+2=b b* b*25%+2=0 b* b* b=-32
Reference: Personal socks.
I have a high rate of correct answers
b*25%+2=0 b*25% =2 =-2 b =2/ b =8 the wer is 8

This is a one-dimensional quadratic equation for Naidou.
Solve it with the matching method.
b²+b+1/4=3/2+1/4
b+1/2）²=7/4
b+1/2=±√7/4=±（7）/2
b1=（√7）/2-1/2
7-1) Grill 2
b2=-（7）/2-1/2
