To simplify the expression 3b^2 - 3b, we first factor out the common factor of 3b. This gives us 3b(b - 1), where b - 1 is the simplified form of the expression. This expression represents the difference between 3 times the square of a variable b and 3 times the variable b.
2a
Divide by 6a: 6a(a + 3b)
By factoring I get x-3 divided by x+3
b is the square root of 5/3
xsquared minus x minus 72
6b^2 - 3b / 3b 6b^2 - 1 or ( 6b^2 - 3b) / 3b = 2b - 1 Or (6b^2 - 3b ) / 3b = 3b(2b - ) / 3b = 2b - 1
(2a + b)(a + 3b)
12b^(2) - 8b = 0 Factor our '4b' Hence 4b(3b - 2) = 0 4b = 0 Hence b = 0 & 3b - 2 = 0 3b = 2 b = 2/3 So 'b' can take either '0' or '2/3'.
No

3x squared minus 25x minus 28
2x squared minus 4
No, unless "a" happens to be equal to 0, or to 1.
