`(3x^2 + 4y) xx (2x + 3y)`

Simplify: (2x + 5y)(3x + 4y) - (7x + 3y)(2x + y)

(3x - 4y)^(2) - (4x + 3y)^(2) = "______" .

Find each of the following products : (3x + 2y - 4) xx (x - y + 2)

Find each of the following products: (i) 5a^(2) b^(2) xx (3a^(2) - 4ab + 6b^(2)) (ii) (-3x^(2)y) xx (4x^(2) y - 3xy^(2) + 4x - 5y)

{:("Column" A ,, "Column" B), ((3x^(2) - 5)- (2x^(2) - 5 + y^(2)) ,, (a) x^(2) + xy + y^(2)) , (9x^(2) - 16y^(2) ,, (b) 2) , ((x^(3) - y^(3))/(x-y) ,, (c) (9x + 16y) (9x - 16y)) , ("The degree of " (x + 2) (x+3) ,, (d) x^(2) - y^(2)) , (,, (e) 1) , (,, (f) (3x + 4y) (3x - 4y)):}

{:(3x + 2y = 4),(2x - 3y = 7):}

The line 3x + 2y = 6 will divide the quadrilateral formed y the lines x + y = 5, y – 2x = 8, 3y + 2x = 0 & 4y – x = 0 in
