4b
This expression can be factored. ab + 3a + b2 + 3b = a(b + 3) + b(b + 3) = (a + b)(b + 3)
3a+ax+3b+bx = 3(a+b)+(a+b)x = (a+b)(3+x)
Gathering like terms together, this is equal to 5a + 3b + 7c.
a+b+2+3=5+a+b
It is: 4b+6
(a+b)(3b+1)
3b
If a + b = 6, what is the value of 3a + 3b?
8a+b+32a+3b=40a+4b
-13
If ( b ) equals 4, then ( 3b ) can be calculated by substituting 4 for ( b ). Thus, ( 3b = 3 \times 4 = 12 ). Therefore, ( 3b ) is equal to 12.
2A plus 3B times 2A - 3B = 4A2 - 9B2; this is an example of the general formula (a + b)(a - b) = a2 - b2.
(2a + b)(a + 3b)
6
This expression can be factored. ab + 3a + b2 + 3b = a(b + 3) + b(b + 3) = (a + b)(b + 3)
-3b=96+b -4b=96 b=-24
2 - 3b = 7b + 12 Let us introduce equal terms (3b - 12 in this specific case) on each side (left and right) of the equal sign, so that the 'b' term is all alone on one side of the equal sign. 2 - 3b + (3 b - 12) = 7b + 12 + (3 b - 12) -10 = 10b b = -1 =============================
