How would you factor 4A² - B²?
4a² - b² = (2a + b)(2a - b)
What is 5ab plus 4a-b-2ab plus 5b?
5ab-2ab+4a-b+5b = 3ab+4a+4b
What does ab over b divided by 4a over 5b equal?
(ab/b) / (4a/5b) =(ab / b) * (5b / 4a) = (5ab2 / 4ab)= 5 / (4b)
What is 4a equals 4-b 4a equals 2-b?
They appear to be the equations of two parallel lines in the a-b plane.
What is the rational expression of the quotient 4a plus b and 2a - 5b?
The expression is: (4a+b)/(2a-5b)

Who can factor 64a6n - b6n?
n(2a - b)(2a + b)(4a^2 - 2ab + b^2)(4a^2 + 2ab + b^2)
What is 4a plus 3c-2b-c plus a-b?
4a + 3c - 2b - c + a - b = 5a - 3b + 2c
Who can factor 64a raised to 6n - b raised to 6n?
n(2a - b)(2a + b)(4a^2 - 2ab + b^2)(4a^2 + 2ab + b^2)
What is a plus a plus a plus a plus b plus b?
a+a+a+a+b+b - add the like terms =4a+2b 4a and 2b cannot be added because they are not like terms.
6a plus 7b - 4a - 8b equals?
6a + (7b - 4a - 8b) = (6a - 4a) + (7b - 8b) = 2a - b
4a plus 2 equals 3b-5?
The equation cannot be solved as there are two unknowns. However it can be simplified and the two unknowns (a and b) expressed in terms of the second unknown. 1) Expressing a in terms of b 4a + 2 = 3b - 5 4a = 3b -7 if desired this could be stated as a = (3b - 7)/4 2) Expressing b in terms of a 3b - 5 = 4a + 2 3b = 4a + 7 if desired this could be stated as b = (4a + 7)/3
