expand (4t+e^t)(4-sqrt(t))

expand

(4 t + e^{t}) (4 - t)

16 t - 4 t t + 4 e^{t} - e^{t} t

Solution steps

(4 t + e^{t}) (4 - t)

Apply FOIL method:

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

a = 4 t, b = e^{t}, c = 4, d = - t

= 4 t \cdot 4 + 4 t (- t) + e^{t} \cdot 4 + e^{t} (- t)

Apply minus-plus rules

+ (- a) = - a

= 4 \cdot 4 t - 4 t t + 4 e^{t} - e^{t} t

Multiply the numbers:

4 \cdot 4 = 16

= 16 t - 4 t t + 4 e^{t} - e^{t} t

\frac{( x + 3 ) 7}{5}

\frac{x ( - 12 x + 13 )}{7 ( 10 x - 1 )}

\frac{ln ( y ) y}{( x + 2 ) ln ( x + 2 )}

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