(-a-7b+5)4ab
(a + 2b)(a + 2b)
a^2b^2(4ab) = 8a^3b^3.
(4ab^2 + 3cd)(4ab^2 - 3cd)
2a(2b) Would Give You The Answer 4ab. 2x2 = 4 And a x b = ab.
4a2 + 4ab - y2 + b2 You cannot simplify this expression because it does not contain like terms, but you can factor it such as: 4a2 + 4ab - y2 + b2 = (4a2 + 4ab + b2) - y2 = (2a + b)2 - y2 = [(2a + b) - y][(2a + b) + y]
(-a-7b+5)4ab
(a + 2b)(a + 2b)
i need help
2a*2b = 4ab
4ab - 2a - 7
Urmm 4ab ?
4ab * 3a = 12a2b -----------
4a2+4ab+b2 in2
a^2b^2(4ab) = 8a^3b^3.
Assuming that non-leading numbers are exponents, the expression becomes12a^2b + 8a - 5a^2b + 2ab - 4ab^2 + 6ab - 2a - 3ab= 7a^2b + 6a + 5ab - 4ab^2= a*(7ab + 6 + 5b - 4b^2)
(4ab^2 + 3cd)(4ab^2 - 3cd)
