expand (c^2+d^2)(e^2+f^2)

expand

(c^{2} + d^{2}) (e^{2} + f^{2})

e^{2} c^{2} + c^{2} f^{2} + e^{2} d^{2} + d^{2} f^{2}

Solution steps

(c^{2} + d^{2}) (e^{2} + f^{2})

Apply FOIL method:

(a + b) (c + d) = a c + a d + b c + b d

a = c^{2}, b = d^{2}, c = e^{2}, d = f^{2}

= c^{2} e^{2} + c^{2} f^{2} + d^{2} e^{2} + d^{2} f^{2}

= e^{2} c^{2} + c^{2} f^{2} + e^{2} d^{2} + d^{2} f^{2}

f (x + h)^{(2)} - 3

\frac{1690 ( 36 + 5 3 )}{407}

\frac{3 ( 2 - 1 )}{2}

\frac{12}{( s + 1 ) ^{3}}

\frac{( x + 1 ) x}{x - 1}
