4b-240-(3b-2a+2b)f]

The factors of 8a^3+b^3-6a b+1 are (a) (2a+b-1)(4a^2+b^2+1-3a b-2a) (b) (2a-b+1)(4a^2+b^2-4a b+1-2a+b) (c) (2a+b+1)(4a^2+b^2+1-2a b-b-2a) (d) (2a-1+b)(4a^2+1-4a-b-2a b)

Simplify: a^2b(a-b^2)+a b^2(4a b-2a^2)-a^3b(1-2b)

4a+[2a-{3b+(3a-2b)]}

Simplify each of the following: -5(a+b)+2(2a-b)+4a-7 -3(a+b)+4(2a-3b)-(2a-b)

Simplify each of the following: -5(a+b)+2(2a-b)+4a-7 -3(a+b)+4(2a-3b)-(2a-b)

-3 (a + b) + 4 (2a - 3b) - (2a - b)

The three points [(a+b)(a+2b),(a+b)],[(a+2b)(a+3b),(a+2b)] and [(a+3b)(a+4b),(a+3 b)]

Simplify: 4a b(a-b)-6a^2(b-b^2)-3b^2(2a^2-a)+2a b(b-a)

If (5a-3b)/a= (4a+b-2c)/(a+4b-2c) = (a+2b-3c)/(4a-4c) , then show that 6a=4b=3c.
