expand 4.9(5-s/(340))^2

expand

4.9 (5 - \frac{s}{340})^{2}

\frac{4.9 ( 2890000 - 3400 s + s ^{2} )}{115600}

Solution steps

4.9 (5 - \frac{s}{340})^{2}

Apply Perfect Square Formula:

(a - b)^{2} = a^{2} - 2 ab + b^{2}

(5 - \frac{s}{340})^{2} = 5^{2} - 2 \cdot 5 \cdot \frac{s}{340} + (\frac{s}{340})^{2}

= 4.9 (5^{2} - 2 \cdot 5 \cdot \frac{s}{340} + (\frac{s}{340})^{2})

Simplify

5^{2} - 2 \cdot 5 \cdot \frac{s}{340} + (\frac{s}{340})^{2} : \frac{2890000 - 3400 s + s ^{2}}{115600}

= 4.9 \cdot \frac{2890000 - 3400 s + s ^{2}}{115600}

Apply the fraction rule:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{4.9 ( 2890000 - 3400 s + s ^{2} )}{115600}

f (x) = (e^{x} + e^{- x})^{4}

x^{4} 6 - x (e^{k} - e^{- z})

\frac{2 s ^{2} + 2 s - 1}{s ^{2} ( s ^{2} - 2 s - 1 )}

\frac{( 5 s + 20 )}{( ( s + 1 ) ( s + 2 ) ( s + 3 ) )}
