simplify-(-z+1(z-4(-6z+5(-9z-7(z-(z+b))))))

simplify

- (- z + 1 (z - 4 (- 6 z + 5 (- 9 z - 7 (z - (z + b))))))

- 204 z + 140 b

Solution steps

- (- z + 1 \cdot (z - 4 (- 6 z + 5 (- 9 z - 7 (z - (z + b))))))

Simplify

- z + 1 \cdot (z - 4 (- 6 z + 5 (- 9 z - 7 (z - (z + b))))) : 204 z - 140 b

= - (204 z - 140 b)

Apply the distributive law:

- (a - b) = - a + b

- (204 z - 140 b) = - 204 z + 140 b

= - 204 z + 140 b

- \frac{17}{4} \cdot \frac{4}{9} + (669.5 \cdot \frac{40}{927})

\frac{4}{3} \cdot 3.14 \cdot 3^{3}

2 a^{4} - 2 b^{4}

\frac{1}{x} - \frac{2}{x ^{2} + x} - \frac{3}{x + 3}

\frac{( 2 - i ) ^{2} - i ^{15}}{3 + i}
