`(5x+7)xx(3x+4)`

Find the each of the following products: (5x +7)(3x + 4)

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

Find each of the following products : (2x^(2) + 3x - 7) xx (3x^(2) - 5x + 4)

Express the following product as a monomial : (x^3)xx(7x^5)xx(1/5x^2)xx(-6x^4)

If f (x) = (3x + 4)/( 5x -7), g (x) = (7x +4)/(5x -3) then f [g(x)]=

If f (x) = (3x + 4)/( 5x -7), g (x) = (7x +4)/(5x -3) then f [g(x)]=

Simplyfy: (3x^(2) + 5x - 7)(x -1)- (x^(2) - 2x +3)(x + 4)

Express each of the products as a monomials and verify the result in each case for x=1: (4x^2)xx(-3x)xx\ (4/5x^3)
