(3b + 7x)(3b + 7x) or (3b + 7x)2
(a+b)(3b+1)
6+7a+6b
add like terms: 3a -2a -5b + 6b +3b - 7b = a -3b
If a + b = 6, what is the value of 3a + 3b?
(3b + 7x)(3b + 7x) or (3b + 7x)2
3b
5 + 10ac + 3b
(a+b)(3b+1)
6+7a+6b
3a + (3b - 2a) + 5b =3a + 3b - 2a + 5b =(3a - 2a) + (3b + 5b) =a + 8b
add like terms: 3a -2a -5b + 6b +3b - 7b = a -3b
(2a + b)(a + 3b)
If a + b = 6, what is the value of 3a + 3b?
1a+3b 2a+4b=3a +7b
8a+b+32a+3b=40a+4b
2A plus 3B times 2A - 3B = 4A2 - 9B2; this is an example of the general formula (a + b)(a - b) = a2 - b2.
