User: Find the product mentally. (2m - 9)2

Weegy: (2m - 9)^2
= (2m - 9)(2m - 9)
= 4m^2 - 36m + 81

User: Find the product mentally. (ab + 3)2

Weegy: (ab + 3)^2
=(ab + 3)(ab + 3)
=(ab)(ab) + (ab)(3) + (3)(ab) + (3)(3)
=a^2b^2 + 3ab + 3ab + 9
=a^2b^2 + 6ab + 9

(n + 7)^2
= (n + 7)(n + 7)
= n^2 + 7n + 7n + 49
= n^2 + 14n + 49

Multiply (6z 2 - 4z + 1)(8 - 3z).
Weegy: (6z^2 - 4z + 1)(8 - 3z) = -18z^3 + 12z^2 - 3z + 48z^2 - 32z + 8 = -18z^3 + 60z^2 - 35z + 8 User: Simplify b(a + b) - a(a - b). Weegy: b(a + b) - a(a - b) (ab + b^2) - (a^2 + ab) = -a^2 +2ab + b^2 User: Find the product.
