expand s(7-12t+t^2+20ln(t+1))

expand

s (7 - 12 t + t^{2} + 20 ln (t + 1))

7 s - 12 s t + s t^{2} + 20 s ln (t + 1)

Solution steps

s (7 - 12 t + t^{2} + 20 ln (t + 1))

Distribute parentheses

= s \cdot 7 + s (- 12 t) + s t^{2} + s \cdot 20 ln (t + 1)

Apply minus-plus rules

+ (- a) = - a

= 7 s - 12 s t + s t^{2} + 20 s ln (t + 1)

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

A (0, 2, - 3)

\frac{( 12 t ^{2} )}{( 1 + 0.3 t ) ^{2}}

\frac{49 x}{( x - 7 ) ( 3 x - 3 )}

(e^{2 x} + 3)^{2}
