Schritte zur Lösung

(7 + 5) (3 - 5)

Apply FOIL method

(7 + 5) (3 - 5) : 16 - 45

= 16 - 45

e x p an d (tan (x) - 1) (sec (x) tan (x))

e x p an d \frac{5832 x ( - 9 x ^{2} + 1 )}{( 1 + 9 x ^{2} ) ^{4}}

e x p an d \frac{e ^{- x} + x}{x ( x ^{2} + 3 x + 4 )}

e x p an d (sin (x) + 3) (sin (x) - 4)

e x p an d 2 (4 - π)
