(2a + b)(a + 3b)
2A plus 3B times 2A - 3B = 4A2 - 9B2; this is an example of the general formula (a + b)(a - b) = a2 - b2.
No. 2a is one thing, 3b is another. If you add them together, they become 2a + 3b. 5ab indicates that multiplication has taken place. 5 times a times b = 5ab
2a x 3b = 6ab
2a+2b+3a+3b+a+b= 6a+6b 2a+3a+a=6a 2b+3b+b=6b
2a+3b+4c cannot be added. They are not like terms. Like terms need to have the same variable in order to be added.
No
The verbal expression of 3b to the second power plus 2a to the 3rd power is "three b squared plus two a cubed."
3a + (3b - 2a) + 5b =3a + 3b - 2a + 5b =(3a - 2a) + (3b + 5b) =a + 8b
2A plus 3B times 2A - 3B = 4A2 - 9B2; this is an example of the general formula (a + b)(a - b) = a2 - b2.
1a+3b 2a+4b=3a +7b
(6ab + 9b)/(2a + 3) = 3b(2a + 3)/(2a + 3) = 3b
11a+7b-(3b-2a)
add like terms: 3a -2a -5b + 6b +3b - 7b = a -3b
8b -2a
2ab - 3b2 - 3b + 2a does not have a solution, as it is not an equation.
6+7a+6b
(a+b)(3b+1)
