simplify (21-2x)((27.5)/2-2 x/2)x

simplify

(21 - 2 x) (\frac{27.5}{2} - 2 \frac{x}{2}) x

(21 - 2 x) (\frac{55}{4} - x) x

Solution steps

(21 - 2 x) (\frac{27.5}{2} - 2 \cdot \frac{x}{2}) x

\frac{27.5}{2} = \frac{275}{20}

= (21 - 2 x) (\frac{275}{20} - 2 \cdot \frac{x}{2}) x

Cross-cancel common factor:

2

= (21 - 2 x) (\frac{275}{20} - x) x

Cancel

\frac{275}{20} : \frac{55}{4}

= (21 - 2 x) (\frac{55}{4} - x) x

\frac{9 x ^{4}}{x}

(a - b)^{3} - 8 (a + b)^{3}

x^{3} + 15 x^{2} - 500

10 u^{45} + 11 u

b f (x) - 9 (x)
