expand (y^3+3xy^2)(5+sec(y))

expand

(y^{3} + 3 x y^{2}) (5 + sec (y))

5 y^{3} + y^{3} sec (y) + 15 y^{2} x + 3 y^{2} x sec (y)

Solution steps

(y^{3} + 3 x y^{2}) (5 + sec (y))

Apply FOIL method

(y^{3} + 3 x y^{2}) (5 + sec (y)) : 5 y^{3} + y^{3} sec (y) + 15 y^{2} x + 3 y^{2} x sec (y)

= 5 y^{3} + y^{3} sec (y) + 15 y^{2} x + 3 y^{2} x sec (y)

\frac{2 ( 4 - 7 )}{3}

\frac{1}{x ^{2} ( x ^{2} + 6 x + 7 )}

(- \frac{x ^{5}}{2} + y) (4 x^{2} - x y + y^{3})

\frac{x ^{3} - 8 x ^{2} + 10 x - 1}{( x - 1 ) ^{2} ( x - 2 ) ( x - 3 )}

2 [(2 + t^{4}) (5 - t^{2})]
